Dear Stata users,

After running a regression with "ivreg2" command, I run "ivhettest"
command for testing for heteroscedasticity. But, I receive the error

. ivhettest, bpg
ivhettest not allowed after ivreg2 with partial (previously fwl) option

Could you tell me what does this mean and how can I test
heteroscedasticiy after an IV regression with panel data.

Thank you.
