I have estimated some equations both with and without weights, and
while the unweighted version gives the F-Statistics at the top of the
results, the weighted version doesn't (it shows a ".").

I have done some searches on why this is the case and so far found
nothing.  I meant to read the [svy] Survey Data but I still haven't
got around to it (sorry - computer runs estimations much faster than I
can read books).  It'd be great if someone can point me to the
resources or an explanation.  If the answer can be found in the [svy]
book please tell me too!

Many thanks for the bandwidth!
