In analyzing weighted survey data, I'm surprised that the following commands
        svyset [pweight=weight]
        svyreg y x
don't give the same results as
        reg y x [pw=weight]
or
        reg y x [pw=weight], hc3
or even
        reg y x [aw=weight]

I'm left confused as to what svyreg is doing. Any insights most appreciated.

Thanks!
Paul
