Hello,
Can anyone please help with following issue?
I am doing xtivreg with endogenous interactions (my endogenous variable is interacted with explanatory variables; I used # to write the interactions).
After xtivreg, I want to run xtoverid but I am not allowed. This error message is returned:

. xtoverid
cLX#cL: operator invalid
r(198);

where X is my endogenous variable.

Thank you
