Hi Grazia,
Look at the xt family of commands for time series panel data. In particular xtlogit. For example the command for your regression would look like this: xtlogit y x1 x2 x3, i(firm) fe
You will also find a host of diagnostics in the manuals or in the help file.
Hope this helps,
Doug

I have an unbalanced panel of firms and times and three other explanatory
variables.
I want to estimate a fixed effect model with fixed effects for: firms and time.
My dependent variable is a binary one (0/1).
How should I proceed in stata?
I added (T-1) time dummies and estimate the model with clogit including firm as
the �group� variable. Therefore, what I did is the following:
clogit y1 x1-xk i.t, group(firm)
Does anyone know if it is correct to include time dummies when using clogit?
How do I check for a firm specific effect?
How do I assess the goodness of fit of the model?
Many thanks
Grazia
