1. Stata documentation includes provides examples of vce(cluster clustvar) with the regress command. Does it make sense to use vce(cluster clustvar) with the logit command? That is, will I be able to interpret the direction and magnitude of the coefficients if I use vce(cluster clustvar) with the logit command?

2. Does it make sense to use the fe option with the logit command? Are the logit command and xtlogit command the same?
