[Gretl-devel] Re: problem with omit --auto=BIC

I'm looking at some related code in git, leading to some questions (although not directly related to the reported failure yet). In lib/src/compare.c there's auto_drop_var around line 1511. In that function, it seems that a first loop picks the candidate variable to be dropped, and always by looking at the minimal t-stat. (if (tstat < tmin) and so on.) Only _afterwards_ does the choice of using an info criterion come into play. (Below, where: "... else { /* using an info criterion */ ...") I can understand why one wants to focus on a candidate variable in each round, but doesn't that contradict the documentation of omit --auto: 'The “best” candidate at each step is then that whose omission gives the greatest improvement (reduction) in the selected criterion.' ??
