Milena, is this something you are after? set seed 123 clear set obs 740 generate sample_level=floor(runiform()*4) generate outcome=runiform()*4200>2000 generate var1=runiform() generate var2=runiform() generate var3=runiform() generate id=floor(runiform()*2) levelsof sample_level, local(levs) foreach n in `levs' { display "" display "======== Regression for level: `n' ====================================" logistic outcome var1 var2 var3 if sample_level==`n', vce(cluster id) } Best, Sergiy On Tue, Nov 19, 2013 at 7:34 AM, Milena Przheska <milena.przheska@cosmicdevelopment.com> wrote: > Dear Statalist members, > > I am trying to fit the same logistic regression model using different > samples from a data set and I am wondering if it is even possible to > use a -foreach- loop to estimate regression models for each sample > (indicated by a variable). > > I use the variable 'sample' to indicate the sample, but instead of > writing the command over and over for each sample, I tried to do this > with a -foreach- loop, something like this: > > egen local sample_level = levelsof(sample) > > foreach n of sample_level { > logistic outcome var1 var2 var3 if sample_level==`n', vce(cluster id) > } > > As always, I would appreciate your help. > > Thanks, > Milena > * > * For searches and help try: > * http://www.stata.com/help.cgi?search > * http://www.stata.com/support/faqs/resources/statalist-faq/ > * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
