Hello everyone,
I am writing because I was wondering what procedure I
could use in STATA or other statistical software to
analyze a dependent variable that has many zeros, if
at the same time I want to use fixed effects or
clustering in the regression equation (because it is a
very short [i.e. 2-period] panel). The fixed effects
or clustering does not allow one to use Tobit. I saw
a reference somewhere to symmetrically trimmed least
squares for this situation. Any ideas how I could do
his or an alternative estimation for this problem?
Thank you for your help,
matt
