Hello all,

I'm trying to translate into Stata a bit of SAS code. SAS does 

fit /equation_list/ itsur

where Stata would say

sureg /equation_list/ isure

The tech folks at SAS told me that their default denominator for degrees of
freedom correction is n-k, where k=# of params, which can be set to n by
adding vardef=n after itsur in the command line above.

What is the default for Stata, and how can it be changed?
