T-test with Sample Weight

[Hajirah Kausar]

Hello,

I wanted to do a t-test using variables age and doctor-diagnosed asthma (ConDr) accounting also for my sample weight which is int121314.
I tried the commands ttest age, by(ConDr) [aweight=int121314wt] and ttest age, by(ConDr) [pweight=int121314wt] got option [ not allowed.
Can anyone tell me what would be the accurate command.
Thank you.

ttest does not allow weights as near as I can tell. Assuming CondDr is coded 0/1, you can set this up as a regression problem like this:

reg age CondDr [pw=int121314wt]

Okay
Thank you.
