Hi,
seems that id is running ok from 1 to 85. I have put -set trace on- but i am afraid i don't understand much. Seems like some versions are missing but i have no idea what these are. What does version stand for?
Thank you
THIS IS THE OUTPUT I GET
. set trace on
. set more off
.
. gen predicted_return=.
(13686 missing values generated)
.
. egen id=group(company_id)
