Hi everybody,
I am a new stata user, so excuse me for my ignorance...I am using panel data and I want to do my descriptive analysis and my exploratory analysis having (of course) the same number of observations. I first rum my prbot model and then I make tables with means using e(sample in my "if" statement and everything goes well. However when I do crostabs (using ta or table) the number of observations is different (higher to be exact). I have observed, while making the means tables, that when I dont include in my descriptives all the variables used in the probit model then the sample size changes. How can I keep the sample size the same without deleting the missings?
Thank you for your understanding,
Dimitris Souftas
