Hello everyone,

I am trying to run the following model

xi: xtivreg sba ids fco vvm nan avi i.year (tnom vda = sud m_vvd m_mmd), be first

I would like to test if tnom vda are really endogenous or exogenous.

I know I can Collapse the data to a cross section and use estat endogenous but my supervisor would like me to keep the years controlled for.

I would appreciate if someone let me know the command.

Thank you very much
Mona
