Dear listers,
I'm facing a very strange Stata behavior. I've a long routine to execute over a dataset in Stata (version 9, updated to 14 april), so I put it in a do file. Two information: the data set is large (17,000 observations) and has complex sample (the analysis use the survey family commands). When I run the do file and write the command for estimation in command window I get the first output below; when I execute the routine from the do file (including the command for estimation) I have the second out below, which is very different from the first one. Anyone has experienced that sometime? Any suggestion to dealing with it? Any ideas about the problem source?
Thanks in advanced
Wolney.
