Hey Richard,

Yes, they do work under version control (specifying version 12) but seemingly take much longer (many more iterations) than when I initially used them under version 13! I am surprised that they somehow got removed from version 13.

It looks to me like aweights work if you specify version 12, e.g.

version 12: qreg y x [aw=awvar]

As to why they used to work and now don't, I don't know. I know that
Stata will sometimes drop support for something if it decides it is
not appropriate. For example, logit used to support aweights, but now
only does so under version control because it was decided that
aweights were not appropriate for logit.

I am mildly surprised that -help whatsnew- does not seem to say
anything about dropping support for aweights.
