If you don't also have stratification and sampling weights, I suggest you
use the cluster() option with something other than the survey commands.
Numerator and denominator degrees of freedom in survey estimation is an
extended discussion, one which appear to be unnecessary in this case.

Subject: st: question about F-test in svyreg 

Hello --

I have a sample of approximately 100 teams from 5 organizations.
there is non-independence across the teams within an organization, I'm
considering using svyreg with psu = 5 (for the five organizations).
When I
run this model, the F has ( 3 , 2) degrees of freedom.   I'm wondering
the F is testing, and how one interprets it in the svyreg function.  In
typical regression, the first number in the df is the number of
parameters/variables in the model (I have 11).     I'd appreciate any
