Hi all, I'm a little confusion with the use of esttab. For example, for each sample I ran two regressions, so the code should be like: esttab model*, mgroups("group1" "group2" "group3" "group4", patterns(1 0 1 0 1 0 1 0)). But the problem is that the title group1 - group4 would always be on the first column of the two. Is there a way to center the title? Thanks!
