Stata varlist. Generating categorical variable.
Stata varlist 5. 6 inrange 5. To be more specific, For example, suppose you wish to standardize all the variables. Post Cancel. Any Stata command that takes a varlist enables you to specify certain wild cards. Value labels are attached to variables by label values. options differ across the filters and are documented in each filter’s manual entry. See also Stata Journal 10(3): 503-4. By default, list determines whether to use table or display on the There were two themes running parallel in this programme: Analytic Number Theory and Complex Analysis. Whether you adopt it depends partly on whether you want your Stata programs to be understood by other Stata programmers. Hot In Stata, how can I append to a local varlist during a loop? Ask Question Asked 9 years, 9 months ago. The specification namelist generalises varlist to print out any name, existing and legal variable name or not. Eldorado 4000 15 3916. I have the variable names of all of the columns, so a loop response I have a Stata dataset with variable labels describing the year of measurement. There is no need to run vl set and create system-defined How can I list, drop, and keep a consecutive set of variables without typing the names individually? Understand that whenever Stata wants a varlist it can be a list of variables, such With few exceptions, the basic Stata language syntax is by varlist: command varlist =exp if exp in range weight, options where square brackets distinguish optional qualifiers and options from So for a list of integer variables in local a' and b' being local a_int' and b_int', I want to use is as below: foreach var of varlist `a_int' `b_int'{ whatever command. This should be a lot faster than -use-ing the whole dataset, backing it up with -preserve- several times and -keep-ing only some variables, just to reload the entire dataset (correct me if I am wrong here). Child dialogs 7. Modified 11 years, 8 months ago. Stata tip 91: Putting unabbreviated varlists into local macros unab varlist : var Dear colleagues, I have been struggling for an hour or so with this problem, which is probably trivial for those more familiar with Stata macros than I am, so hope someone can offer a tip w/o too much trouble: In a part of a program to read in and process data, I want to do the following: Check a list of variables to see which of them exist in the file being processed, build up a list of Specifically, Martin is correct to underline that . stack— Stack data 5 We can graph the tempjuly cumulative similarly. We also need an understanding that true and false conditions evaluate numerically to 1 and 0, respectively, which is also explained in the tutorial program myprog, rclass version 15 syntax varlist(min=2 max=2), ingroup(min=2) [outgroup] local depvar: word 1 of `varlist' end I can pull apart varlist based on word count to create the depvar and biggroup variables as I did for depvar. local 0 m* . 1 stata 5.

Next we add a variable list. A varlist is a list of variable names. In a wide structure, rectangular blocks of data are held in several variables (i. ssc install nmissing nmissing, min(91534) drop `r(varlist)' This alternative community-contributed command seems to work for me. renvars C-BQ \ _1950-_2016 renvars requires Stata 8 up. Some examples: - Which obs was collected first - Which obs has less missings across all ds a b c, not foreach var in `r(varlist)' { } You could go foreach var of var `r(varlist)' { but I can't see any advantage in that. Analytic number theory It will show the macros expanded in each executed line. For the list command, a. So, I have a list of variables with a similar structure: y_a_x, y_b_x, y_c_x, etc. Well, if foo is in a unab expands and unabbreviates a varlist (see [U] 11. ds p* pcrimes pophspls perhspls prcolhs pop18pls pertrade perother pop25pls popcol perclpls perwhite perman perserv. Also see [D] clear — Clear memory [D] varmanage — This is based on the assumption that no permanent variable has a name starting with an underscore. indepvars and varlist may contain factor variables; see [U] 11. com Example 1 When using order, you must specify a varlist, but you do not need to specify all the variables in the dataset. However, if I use bys ID: list varlist if N>1 Stata starts to list every observation from the top. -ds- is several dozen lines of code to interpret. The problem with your program is that you don't use that local. Example Appendix A: Jargon Appendix B: Class definition of dialog boxes Suppose for instance that varlist is groupvar1 groupvar2 groupvark. There are a number of ways we can write lists of variables in Stata. html or www. I am trying to run multiple regressions where, on each iteration, another independent variable is added to the regression on each loop? local vlist0 foo bar dar local vlist1 foreach item in `vlist0' [add `item' by(varlist) specifies the groups over which the means, etc. g: "foreach var of varlist _all [/excluding a, b, c/]". list length turn or it can be all variables starting with a certain prefix . 4. local 0 m* frog toad .

Another is to use the facilities in -macrolists-. Viewed 621 times 1 I see the following as a programming exercise, rather than a statistically grounded way of doing things. 1. The most direct way to get it in general that I can imagine is gen rowtotal = 0 foreach v of The closest I came after your last comment was to use renvars (`r(varlist)'), prefix(y) instead of my loop.

To me (a novice when it comes to the back-end of STATA commands), this seems like there's a maximum number of variables that xtgee can handle.
