Stata store value

Stata store value. label define region 1 "North east" 2 "North central" 3 "South" 4 "West". Let’s save this data and call it auto2 (Stata will save it as auto2. : Locals can be used to store mathematical expressions with a slight change in the syntax we are already familiar with. specify a custom missing-value code to use in worksheet. When Stata launches, it creates a frame named default, but there is nothing special about it, and the name has no special or secret meaning. Clyde Schechter. 11Obtaining predicted values 20. Through this, one also obtains the median in form of the 50% percentile. This allows the user, as well as estimates store name stores the current (active) estimation results under the name name. Speaking Stata: How to move step by: step. Candice Yandam. In this case, we’ll use the name The problem is that this program displays a value that is different from the mean of weight of the auto. Your command "local label `v' = foreign" gets seen by Stata as "local label = foreign". In this example, the local called local1 will store the value 10. Your second code does the initial xtreg squaring SE281 but the second xtreg does not, and thus it is producing residuals for a different model than the one that produced the coefficient estimates. Variable Storage Display Value name type format label Variable label make str18 %-18s Make and model mpg int %8. The maximum value of matsize is 800 for Stata/IC, so matrices are not suitable for holding many data. Stata does not save matrices with the dataset.

The Stata Journal, 4(4):486-487. double speciﬁes that the results for each replication be stored as doubles, meaning 8-byte reals. That almost always means that it really is forbidden. So, there are a couple of problems with your code. These commands run the Stata commands on the specified frame, and switch back to the original frame once they are finished. You can use a loop to populate your data set with the coefficients as appropriate. list alpha 1. xlsx, firstrow clear (12 vars, 74 obs). Stata: Extracting values and save them as scalars (and more) 2. A more experienced user can probably say more. Also see[D] compress,[D] destring, and [D] frunalias for alternatives to recast. I am assuming you would want the coefficients as the values for the variable for their corresponding group observations. I know I can get the result of a single centile using r(c_#). My first guess was that it might be some system variable (like _b or _se in the case of regressions) / global macro where the p-value is stored, but after reading the old messages from Statalist I've seen that it is not so, but on the other hand STATA provides us with the tools to calculate the p-value. We will compute a variable called price3 which will be three times the value of price. More generally, different Stata commands return different results. com matrix mkmat — Convert variables to matrix and vice versa DescriptionMenuSyntaxOptions Remarks and examplesAcknowledgmentReferencesAlso see Writing strL variables is not yet supported. You also have the option of setting up the environment variable, STATATMP , to point to a location other etable— Create a table of estimation results 7 bgcolor, fgcolor, and color may be one of the colors listed in the Appendix; a valid RGB value in the form ### ### ###, for example, 171 248 103; or a valid RRGGBB hex value in the form #####, for example, ABF867. Hi all, I am running some SEM models and would like to store/save some values from the output table as scalars. model or to compare the estimated values of those coefﬁcients. 0gc Pop, 5 to 17 years pop18p long %12.

Writing scalars into a file in Stata. 5, 6, 6. The command is useful for exploring data where the records refer to more than one level, for example longitudinal data Evidently, some of these phrases have apostrophes in them and I do not know how to store them. Search in General only Advanced Search Search. But I am calculating 50 centiles, and want to store all of them in one local vector/matrix without having to I have a need to store dates as strings and can't seem to find an easy way to do this.

Stata: Generate a loop to save regression output as new variable. we wish to format the means and p-values to display two digits to the You can frame change, issue the Stata commands, and then frame change back. Typing compress every so often is a good idea. export value labels or the underlying values. I need the value I get using "egen sum(x)", but not the column of these values, but just a single number which stata would terat as a scalar. If 1 did not correspond to any mapping within the value label, or if the value label forlab were not deﬁned, 1 (the # itself) would be returned. My goal is to store the median. To insist on a map from missing to Either way, that code will indeed fail if it meets a string variable. You might type . I hope this helps.

The store-completed option may be speciﬁed only if the data are ﬂong or ﬂongsep; see[MI] mi convert to convert to one of those styles. The main differences are: Specify the names and values of the scalars in pairs. It is also possible to get more sophisticated measures via the summarize varname, detailoption. Similarly for temperatures between 20. The set-up. Here %s refers to the numeric value that is formatted as speciﬁed using nformat(). I see 'unique' or 'distinct' commands will show the total number of unique values in the variable, but they don't actually list each of the unique values. M. Such a check for equality need to be treated carefully, especially when the value is a #4 mentioned installation from SSC. 1666667 and I want to generate a new variable that would be these numbers but truncated to two decimals. Syntax List results Title stata. Roger--Roger Newson Lecturer in You can make Stata try all those values and trap cases when there is no output. In the auto dataset, repair record is missing in 5 observations. Home; Forums; Forums for Discussing Stata; General; You are not logged in. 0gc Pop, 65 and older popurban You can do the above by using by:, which is one of the most versatile features of Stata. Stata allows you to label your data file (data label), to label the variables within your data file (variable labels), and to label the values for your variables (value labels). I would need to export it to excel, each variable in a row, with value and value labels. scalar list If you wanted this to be stored in a variable as a number you would type: . Let’s use a file called autolab that does not have any labels. So when you get to -qui sum `varname'-, varname is, in fact, an undefined macro, which is interpreted as an empty string.

Also, for the three references posted by Dirk . In Stata I would like to do the same I have not found an easy way to do this For example, I import new panel data for 20 Countries - if available, for a timespan over 20 years - a max of 20*20 values. For example these two are different jobs, but I am going to do two things in STATA: (1) loop a regression over a certain criteria for many times; (2) store a certain coefficient from each regression results. # Title stata. It creates a table that indicates which coefﬁcients were estimated in each model and, if requested, reports the In Stata I would like to do the same I have not found an easy way to do this For example, I import new panel data for 20 Countries - if available, for a timespan over 20 years - a max of 20*20 values.

Another way of working with frames is . Example 4 The expression "this"*3 results in the string "thisthisthis", whereas the expression 2*3 results in the number 6. The conventional levels of significance are 0. regress mpg weight displ i. I'd like to see all unique characteristics from the particular variable (type: string), excluding all duplicated one. ) Skewness is a measure of the lack of symmetry of a distribution. One clue to by: being useful here is the structure of a grouping of the variable x into several distinct values. Dear Statalist, Is it possible to get MEDIAN value in STATA. 2Data types— Quick reference for data types Precision of numeric storage types floats have st: Save coefficient p-value in matrix.

You can get a list However we do it, keeping track of missing values can save you from some messes. foreach i of num 1/20 { . To my point in #7, when presenting the results, most people are interested in whether the coefficient of a variable is significant and not necessarily the actual p-value. 584–586 Stata tip 53: Where did my p-values go? Maarten L. The default behavior is to scan string columns to get the largest string, but it can be time-intensive. In help data_types we read: "Numbers are stored as byte, int, long, float, or double, with the default being float. For instance, to place --- hai guo <[email protected]> wrote: > I want to store the correlation coefficient into a > variable. It may require a bit more effort to calculate further results but this is easily programmable and if you need to do something often you can write a wrapper program for the command.

Monza domestic 4. Because age21p can take on only 0 or 1, it would be more economical to store the variable as a ereturn list lists the names and values of the macros and scalars stored in e(), and the names and sizes of the matrices stored in e() by the last estimation command. FWIW the SSC version of univar was superseded by an update in the Stata Technical Bulletin in 1999. Could anybody please tell me how can I save an outcome to a variable. A two-dimensional A. bysort rep78 foreign: egen mpgmean = mean(mpg) . The compress command reduces the amount of memory required to store the data without loss of precision or any other disadvantages; see[D] compress. 0gc Population poplt5 long %12. However, simply listing out the p-value isn’t always enough, especially when preparing your findings for a variable measuring a person’s age and you wish to create an indicator variable denoting persons aged 21 and over, you could type. For instance, after linear regression, predict newvar creates x Remarks and examples stata. If you intended something different and want to store values, you can set up a variable (to write into) with all missing data before the loop, run the analysis in the loop (with an if statement), and then replace the values in the set up variable with the same if statement. dta).

How can I correct this? My second problem is : I would like to design a estimates store to store each set of estimation results in memory so that they can be accessed later by estimates table. I present the OR & the 95%CI - is it possible to present the p-values in the same table (eg, in the next column). Stata for Windows, Mac, and Linux can directly import data and export data and results to Microsoft Excel files. " Some people actually want the default to be double, so it is all relative, I guess. 3 Value labels. This option overrides the fvwrap setting; see[R] set Stata: Data Analysis and Statistical Software . For example, if the 10th percentile has a value of 15. exists() is useful because you could store the notfound value in an element. 001, 0.

The maximum When we have survey data, we can still use pctile or _pctile to get percentiles. First off, the syntax diagram for the local command (e. 474,025 ). ereturn post clears all existing e-class results and stores the coefﬁcient vector (b), variance– covariance matrix (V), and constraint matrix (Cns) in Stata’s system areas, making available all the postestimation Let me note another shortfall. If so, when I began using Stata in a serious way, I started by reading my way through the Getting Started with Stata manual relevant to my setup. Another question, how to show the full row/column names and avoid truncation, such as the one below: Code: mat A = 1,2,3\4,5,6 mat colnames A= redbrickhouse greengrasshouse yellowwallhouse mat rownames A= HI Jae, you did not tell us what version you were using, so the code above works in Stata 16. The It looks like your problem was solved, but I will add a solution that would take advantage of the stored results from reghdfe and some linear algebra. frame framename { stata_command stata_command. See the We can obtain the predicted values by using the predict command and storing these values in a variable named whatever we’d like. In Stata, when you fit a model using factor-variable notation, the labels appear in the Using Stata’s stored calculations reduces input errors and improves accuracies. For instance, tabstat height would present the overall mean of height. 2. I am using Stata 14. 96 to construct your confidence intervals which, depending on the number of observations and regressors, may not be a good approximation for the underlying t-distribution. You can create frames, and delete them, and rename them. This seems to be an element of language design. Example 1: Compare coefﬁcients across models To compare coefﬁcients from two or more models, we ﬁrst need to store the results of each model using estimates store; see[R] estimates store. Stata also has the values of system parameters and certain constants such as pi stored in c(). I guess the possible command could be "scalar yxul = *****", but I am not sure how to write the ***** part. Extracting the results from regressions in Stata can be a bit cumbersome.

This is the case because survey characteristics, other than pweights, affect only the variance estimation. I am using the command centile in Stata. 5 upper dummies, or should I just create 2 separate loops with Stata: Data Analysis and Statistical Software . A superior model is the model with the lowest value of information criterion. For instance, label forlab 1 might return Foreign cars if forlab were the name of a value label and 1 mapped to “Foreign cars”. We can similarly explore the data using marginsplot after mean with I see 'unique' or 'distinct' commands will show the total number of unique values in the variable, but they don't actually list each of the unique values.

By default, they are stored as floats, meaning 4-byte reals. Here's what happened when I followed your example: . ) Sorted by: mpg Note: Dataset has changed since last saved. The variable name is the name we use to tell Stata about a variable. But I am calculating 50 centiles, and want to store all of them in one local vector/matrix without having to Splitting values in Stata and save them in a new variable. These statistics can be calculated averaging over all covariates, or at ﬁxed values of some 6mean— Estimate means Example 4: proﬁle plots and contrasts Theﬁrst examplein[R] marginsplot shows how to use margins and marginsplot to get proﬁleplots from a linear regression. I need to export the information on all the variables, such as name of the variable, variable label, values for categorical variables and value labels in the dataset (the database has observations). 05 Feb 2019, 20:54. return list lists results stored in r().

So, the question actually is how to extract a specific value from a matrix and store it as a scalar. For example, in the –sysuse auto– database, “foreign” is labeled as “Car origin”, 0 is “Domestic”, and 1 is “Foreign”. gen var1 = a ‘var1’ will not have the value of ‘a’, rather it would take on the value represented by this scalar, which is ‘123’. 2 are reflected as 20. 2 Compressing data Stata stores data in memory. Notice: On April 23, 2014, Statalist moved from an email list to a forum, based at statalist. How to save regression coefficients to file in SAS?` 1. After reshaping my dataset using the reshape command, some of the variable and value labels are deleted. ip6. You begin with the datetime variables in your data however they are recorded, such as 21nov2006 or 11/21/2006 or November 21, 2006, or 13:42:02. Normally can use the inlist function to do this manually, but I'd like to soft-code it so I can run the program with different sets of values. di `foo' 2-1 If some values are negative, watch out. The equality sign tells Stata to store the evaluated result of the expression we specify (instead of storing that expression as a string). I am wondering if someone can give me a concrete example how to do Stata 14. 5. For example, we can also define a scalar as follows: If you intended something different and want to store values, you can set up a variable (to write into) with all missing data before the loop, run the analysis in the loop (with an if statement), and then replace the values in the set up variable with the same if statement. list make foreign make foreign 1. We expanded the functionality of the table command. levelsof var1 if ridccp == 1, local(cm) gen test=1 if var2 == "`cm'" Most Stata regression commands (including probit) output coefficients to the matrix e(b). See[D] inﬁle eststo is an alternative to official Stata's estimates store. in Stata, value labels are treated as separate objects of the data structure. To my understanding, the feature that allows code the code in #7 to work wasn't added until version 16, so you will have to to use -colnumb()- and -rownumb()- like you did in #5. Although the -syntax- statement allows you to specify varname, a peculiarity is that the resulting variable name is not stored in `varname', it is stored in `varlist'. Rather than returning the contents from the Stata In addition to the output in the shown in the results window, many of Stata’s commands store information about the command and it’s results in memory. (If you hadn't put the -qui- prefix on you would have seen that. For example I want to know Median weight or age of adults of my survey population. I thought that there could be a way using a function as table and storing some r(). perform multiple comparison correction) What's going on this that Stata automatically stores certain quantities after estimation and test commands. 1). Therefore, point estimation of the percentile for survey data can be obtained with pctile or _pctile with pweights. I was not able to find any suggestions online or in the statalist . The skewness of the distribution is 0. So instead of a two-step process where I calculate the mean, then subtract the answer from my education variable, I can simply ask Stata to subtract it’s stored mean Stata keeps data in memory, and you should record your data as parsimoniously as possible. Stata Clarification: if I have a variable with three unique values, a, b and c, I want to store those in a macro variable so I can later take another dataset and select observations that match one of those values.

All we need to do is tag the first occurrence of each distinct value, and then count those first occurrences in sequence. gen gini = real(r(gini)) Hope this helps, Jeph GUO Lei wrote: Dear all, I'm not familiar with Stata yet. If, however, there is more than one alpha or more than one beta, Stata always selects the data-variable interpretation in preference to the scalar. 11.

Tags: None. 0 trying to store a variable value from one observation in a local macro (if the variable is a string) or in a scalar (if the variable is numeric). 6 Creating matrices by accumulating data below. Comment. I'm using Stata 16. respectively. Your closing question is about identifying cases (Stata says observations) for which a variable takes on a particular value and the answer is like . In the first three commands above, those missings would map to 0. For example, after most nofvlabel displays factor-variable level values rather than attached value labels. Hot Network Questions Holomorphic homotopy conjecture Tikz Drawing: Coordinate System with Origin on Curve Firefox snap won't save websites Stata: Extracting values and save them as scalars (and more) 2. I then tag that >observation with a code and append it to a new data set. 2008. Putting string values into a macro using levelsof and then pulling them out again is (1) indirect and (2) tricky, as spaces complicate any extraction based on words. 29 Oct 2018, 00:09. I have a variable named "score" (float) as showed below and I want to truncate it to two decimals. It lists out all the statistics calculated by the last command, including the number of observations (r(N)), test statistics like chi-squared values (r(chi2)), and crucially, the p-value (r(p)). bonferroni makes the Bonferroni adjustment to p st: store means as a new variable. The storage type (otherwise known as the data type) is the way in which Stata stores the data in a variable. ) If you type summ x scal sidney=r(sum) then the scalar -sidney- will contain the sum of x. dta. Options all is for use with return list and ereturn list. 2002. The following example illustrates my approach, which involves creating a new variable and sorting the data in each will work, except that "blood pressure value" is not a valid Stata expression due to the embedded blanks.

Olds 98 domestic 3. This option overrides the fvlabel setting; see[R] set showbaselevels. Stata 18 offers another new command, dtable, that easily builds and exports a table of descriptive statistics, often called Table 1 in publications. I can't find it. You should not do that, of course. I There are no stored results for p-values after regress command. Please see my example below. This gives >me a coded merge-able dataset Hello everyone, I have a question about the use of variable labels. 2. Let’s use the classic 1978 auto dataset that comes with Stata. 2 and 23. We also developed an entirely new system that allows you to collect results from any Stata command, create custom table layouts and styles, save and use those layouts and styles, and export your tables to most are unlabeled values), the values themselves are used, provided that they are nonnegative integers. Is there a command for this? Thank you! as a double but would now be satisﬁed to have the variable stored as a float, even though that would lead to a slight rounding of its values. local foo 2 (-1) . It does not have an option to save the value or variable labels of the variables that How do I find out what stata called the variable?

Chev. help local gets you there) doesn't show that it's allowed. 98. Wencke, You can use -egen- to generate variables with the mean and standard deviation. Results of calculations are stored by many Stata commands so that they can be easily accessed and substituted into later commands. Stata tries its level best in some contexts to find expressions and evaluate them. vu. Once the data is appended, do a wholesale destring. The tag() function of egen goes back a long way in Stata (1999) and just encapsulates a longer-standing trick that I guess is in the manuals somewhere and/or was discussed on Statalist in the 1990s (all the old posts have disappeared). label values region region. 1 2. capture noisily A cookie is a small piece of data our website stores on a site visitor's hard drive and accesses each time you visit so we can improve your access to our site, better understand how you use our site, and serve you content that may be of interest to It looks like your problem was solved, but I will add a solution that would take advantage of the stored results from reghdfe and some linear algebra.

You can rename it. Noninteger values, negative values, and labels that are not valid Stata names are substituted with a default identiﬁer. 95, and the kurtosis is 3. If you make your own Stata programs and loops, you have discovered the wonders of automating output of analyses to tables. 2020. star(#) speciﬁes the p-value cutoff for correlation coefﬁcients to be marked with a star. I cannot get the code to work because Stata does not allow "if" when defining I want to store the distinct values of a variable of my dataset in a local macro. 2023. 666667 and 2. describe Contains data Observations: 74 Variables: 12 Variable Storage Display Value My first guess was that it might be some system variable (like _b or _se in the case of regressions) / global macro where the p-value is stored, but after reading the old messages from Statalist I've seen that it is not so, but on the other hand STATA provides us with the tools to calculate the p-value. Option all is for use as a double but would now be satisﬁed to have the variable stored as a float, even though that would lead to a slight rounding of its values. ). I would like to know then, how many values I have of the possible 400! Title stata.

Thanks again Steve. The new ﬁle is not in Stata format; see[D] save for instructions on saving data for later use in Stata. In a typical approach, a set of potential models is selected, and a superior model is selected from the values of information criteria. How can I achieve this? Thank you for the help. When you generate a variable and the expression evaluates to a string, Stata creates a string variable with a storage type as long as necessary, and no longer than that. Log in with; Higbee, K. With respect to identifiers, they should remain string; there's no expectation of doing math with their value. 6matrix mkmat— Convert variables to matrix and vice versa References Gould, W. Because these values may be referred to but not assigned, the c-class is discussed in a different entry; see[P] creturn. 16. 2Making in-sample predictions All Stata commands that ﬁt statistical models—commands such as regress, logit, and You can use the postestimation command estimates to store estimation results by name for Welcome to Statalist! It sounds like you're starting to use Stata in a serious way, not just to make it to the end of the semester. Scalars can also store the result of an operation as well. You don't say where you want to save them. 5 etc meaningrounding each value off to the I have a repeated measures data set and I would like to create a line graph of the mean values of test scores at each of seven timepoints for four groups: white males; black males; white females; black females; which are coded as a pair of dummy variables (female, black) Y-value is testscore, X-value is month (1-7) etable— Create a table of estimation results 7 bgcolor, fgcolor, and color may be one of the colors listed in the Appendix; a valid RGB value in the form ### ### ###, for example, 171 248 103; or a valid RRGGBB hex value in the form #####, for example, ABF867. However, I have some issues getting levelsof to work. I'm trying to create a new dummy equal to 1 if another variable equals any of the values stored in the local. The text will be placed around the numeric values in your table as it is placed around %s in this option. Rather than returning the contents from the Stata dataset, these commands change those contents to be as given by the last So yes, the p-values that you calculate are already displayed in the regression table. buis@fsw. xls and . sysuse auto, clear codebook mpg, compact Number of unique values of mpg is 21. Speaking Stata: Replacing missing values: The easiest problems. I'd like to access directly to some values in the matrix stored. For example, if I run the following, could I also present the p returns the label value of # in valuelabelname. In the last, they would map to 1 because missing is treated as larger than any known numeric value. This is one of the primary uses of estimates table—comparing estimation results:. Stata tip 14: Using value labels in expressions. rocfit fits maximum likelihood models for a single classifier, an indicator of the It does not sound as if you really need to store multiple numerical values in a macro for your purposes. References Cox, N. ; Reading binary ByteArray data is not supported, only strings. -copydesc- is only of real use to people still using Stata 6 or 7. You can use the postestimation command estimates to store estimation results by name for later retrieval or for displaying/comparing multiple models by using estimates, or for saving them in st: store means as a new variable. Stata’s roccomp provides tests of equality of ROC areas. frame framename: one_stata_command. I'd like to see all unique characteristics from the particular variable (type: My first time posting on this forum. com Remarks are presented under the following headings: Estimation-sample predictions All estimation commands store the b I want to create a list with all of the values (strings) of a particular variable when this dummy is 1. di `foo' 1 . 0g cenreg Census region pop long %12.
