Perform weak instrument test for two endogenous regressors

[Roxanna Sh]

Hi all,
From my understanding weakivtest only works when we have one endogenous variable. Is there any specific test for the weak instrument when we have two endogenous variables?
I also tried estat after ivregrss and it only works with one endogenous variable.

Thank you

I also have a follow-up question. Does 3sls have a test for overidentifying restrictions?
