Hello everyone,

I am trying to write this

Code:
xtpoisson patents cl.ln_xrdintensity##cl.Numberofmergers cl2.ln_xrdintensity##cl2.Numberofmergers cl3.ln_xrdintensity##cl3.Numberofmergers l.ln_emp i.YearEffective i.AcquirorPrimarySICCode, fe vce(robust)

out as an actual regression formula. "l_emp", "YearEffective" and "AcquirorPrimarySICCode" are control variables. Is this the right way?

Array


Best regards

Chris
