Hi José, from section 22.5 in the guide (and also checking the doc for
the --cluster option for the ols command) I tend to think that in gretl
currently these are mutually exclusive options, so it wouldn't currently
be possible. Maybe someone with more experience in this area can weigh in.

I'm noting that combining the --cluster and --jackknife options does not
produce an error, however. While this would be correct according to the
spec (cluster just overrides), I wonder whether it's a good idea to
effectively ignore an unsuitable option silently. If a user wants to
override, couldn't she be expected to remove the jackknife option
explicitly? But that's a different issue not directly related to your
