Hi Stata Community, I'm running some regressions using Fixed Effect Methodology. The issue is that the outcome of my regression shows very large T statistics for some of the variables. I would like to have your thought about ( is this a good sign to have T statistics above 100) or there is an issue that I need to fix. I also noticed that the F test is not reported and only dot is shown. Any could explain what is the issue and how it can be solved?
Thanks a lot for your help in advance.
