Dear Statalisters,
I am estimating a cross-section with WLS, and someone suggested me to use
the command wls0. I know how to use it, but could not find any information
on how Stata calculates it.
I got quite different results when running the same equation (with and
without the constant) by weighted OLS, and I was wondering whether anyone
knows how to get more information on how wls0 it is calculated.
Thanks very much!
Andrea
