This is being worked on.

I think Andreas means the classic table with total/explained/residual
sums of squares and corresponding degrees of freedom.

Now, I *personally* don't like it very much; if you ask me, the best I
can say for it is that it's redundant. Moreover, it's rather easy to
build it via user commands and "$" accessors, if one wants. But it'd be
easy to add an --anova switch to ols (and corresponding checkbox) if
popular demand requires it.

For my take on this subject, see

If I could go back in time, one of the things I would do is campaign
vigorously against locale-dependent decimal separators in gretl, at the
cost of a hunger strike. But it's too late now (and by the way, some
people seem to like them, so I guess I'll just shut up).
