Dear respected Members,
I’m not professional in Stata. Sorry, Pls could anyone help and offer me an explanation with regards to the below question(s);
  1. In regards to panel data set, can I use logit instead of xtlogit? The idea here is, I want to cluster standard error at (id) level, and I have seen in the Google sites that if I want to cluster standard error at (id) I must use logit not Xtlogit! Pls, anyone help for this case?
  2. Well, as I indicated above about the logit model, I have seen in this website that the e (r2-p) for the conditional fixed effect, and e (chi2) for random-effect specification. However, I saw one paper related to my topic (they used logit model ) and in the paper table I have seen this (Pseudo R2 (%) , LR chi2, Prob > chi2) . well, in this case what they used : random or fixed , logit or xtlogit ?
  3. The reason that brought me to some concerns, when I used fixed effect, almost all observations dropped because I don’t have a lot of (Yes) in the dep Dummy and many years without yes ? In regards to the question one, if I must use xtlogit, can I use random effect?
  4. Or you recommended me to reduce the sample even to have balance between yes and no? Take into account that I have 750 instituions only 300 out of them have yes but not all the years and the rest all of them have NO. Is it ok with statistics standpoint? Thanks a lot. I really appreciated.
Kind Regards
