I could need some help regarding the estout command for xtlogit, and I would really appreciate any suggestions on this issue. Being this the case, and knowing how for most data simple logit and probit models produce very similar results, Absolutely, Stata's xtlogit, fe (or clogit, on which the former relies) estimates the maximum likelihood conditional on the sum of the outcomes $\sum_t y_{it}$, so that the incidental parameter problem is taken care of. So the progression of the odds of the outcome is determined by the coefficient of time. How can that be done? regards, ajay Home Forums Forums for Discussing Stata General You are not logged in.

Example 1 We use the data from the “Television, School, and Family With binary dependent variables, this can be done via the use of conditional logit/fixed effects logit models. I'm having problems in order to obtain marginal effects after xtlogit fixed effects. The most common approach is reporting the average marginal effects for whole I understand that the way to model this outcome is to use xtlogit, and the first step is to find out whether fixed or random effects estimation is appropriate. That is why the first example fails. > Even if the dataset is -xtset panelvar >> I have a dataset with 8000 clusters and 4 million observations.
