## st: Missing F-Statistics in estimation results, why?

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!

Regards, Ada
