Hello,
This is my first post here in the forum, but I have frequently visited this forum. Very useful information here, thank you!
I have a very specific question: What's exactly the grand mean used by "margins gw." command?
I find that, after logit regression (see and example below), the differences between levels of a factor variable (e.g. "race") are the same with "margins" and "margins gw.":
However, the considered grand mean is not the same. Why "margins gw." doesn't use the grand mean given by "margins"?
