Hallo everybody
I ask for your help to manage an issue as described in the object of this post.
I am using xtologit command to perform some estimations on a really wide dataset. I have a dummy that split the sample in 2 periods (before and after the crisis)... Now, when I run the command using the whole sample, everything works fine... When I use only the crisis sample, everything works fine (too). However, when I use only the pre-crisis period, the "non concave" routine start; yesterday I didn't manage to find a final iteration. I solved stopping the program. I tried also using just a couple of covariates and the issue remains. Why can I complete the task with a huge (complete) dataset and not using just an half of it?
Thanks
