No over-identification test allowed when using svyset and ivregress 2sls?

[Chan Sap]

Dear All,

I wanted to seek your guidance on how to do over-identification test when I survey set (svyset) the data and use ivregress 2sls. The regression I run looks like this:

syv, subpop(sample1): ivregress 2sls dependent_var independent_var (endogenous_var=instrument_var), first
estat firststage
estat overid

The post-estimation commands yield an error message

 estat firststage
invalid subcommand firststage
r(321);

estat overid
invalid subcommand overid
r(321);

I am using DHS data and am using svyset to account for the survey attributes. It would be much easier to do it with ivregress2, but it is not allowed when I use svyset. Do you have any suggestion on how to do the post-estimation test if I use svyset?

Hello Everyone!
Are there any suggestions for post estimation test to conduct when you use either IVprobit or ivregress 2sls?
Thanks.
