问题 In Stata, I would like to be able to bring value labels up into variable labels when reshaping wide. My raw data looks like this: patient hosp_id hosp_name charges Andrew 1 Springfield General $10 Barry 1 Springfield General $20 Crista 2 Lincoln Medical Center $10 Doris 2 Lincoln Medical Center $15 Ellen 1 Springfield General $15 Faye 3 Memorial Hospital $35 I then label the values of hosp_id and reshape wide . label define hosp_names 1 "Springfield General" 2 "Lincoln Medical Center" 3

问题 I have to save an R-dataset in Stata's .dta format. The dataset contains, among other data, a single column containing long strings (column 3). test data: r_data <- data.frame( ae= 1, be= 2, ce= "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet"

问题 Is it possible to execute a Perl script within a Stata .do file? I have a Stata .do file in which I make some manipulations to the data set and arrange it in a certain way. Then I have a Perl script in which I take one of the variables at this point, apply a Perl package to it, and make a transformation to one of the variables. In particular, I use Perl's NYSIIS function, resulting in a very short script. After this output is provided in Perl, I'd like to continue with some additional work in

问题 I have the following text: This sentence contains a certain date which is 06-08-2003. On this date, 29-12-1945 my grandmother was born. 12-04-1997 was an important year for celebrations. I would like to get the date in a variable but the substr() function does not seem to work? 回答1: You do not show us your code so we cannot tell you what is wrong with substr() . That said, the substr() function works as intended if you know the position of the desired item in a string . In this case, the

问题 Say that I have data like this: group value 1 fox 1 fox 1 fox 2 dog 2 cat 3 frog 3 frog 4 dog 4 dog I want to be able to tell if all values of value are the same within group .

问题 I am used to R-studio for R, which has some features such as guessing what function you are trying to type, by pressing TAB . However, I can't find any integrated development environments (IDE) for Stata. Is there one? 回答1: There is no full-blown IDE for Stata. The question comes up pretty often at Stata User Group meetings, and StataCorp developers always say that they work in text editors. See http://fmwww.bc.edu/repec/bocode/t/textEditors.html -- there's plentiful customization for syntax
