Dear all,
Why is it that when I use aweights in sureg command the parameters are the same as those obtained from seraparate OLS regressions using pweights?
For example:
sureg (y x1 x2) (z x1 x2) [aw=weightvariable]
produces the same parameters as:
reg (y x1 x2) [pw=weightvariable]
reg (z x1 x2) [pw=weightvariable]
I am in fact working with pweights for a complex survey and since I cannot use pweights with sureg I tried aweights instead to see what parameters I would get.
Any kind response on that would be much appreciated.
Thanks
Pedro
