Can anyone tell me why the OVERID option on IVREGRESS needs the FORCEWEIGHTS option when using data with sample weights. Also, how do I determine if my results are valid afterwards?
There is a blurb in the documentation that the reported critical values may be inappropriate with weighted data and I'm trying to determine if I can trust it in my case.
Any references you can provide would be helpful.
Thanks,
C.J.
