Dear Statalist,
I run this command:
reg3 (normscore l1 b2b age l4a l11a l10) (expshare b2b l1 age normscore l4a)
And obtained this results. Could you please tell me if the Std. Error
found for the expshare variable may invalidate the analysis or create any
robustness problem?
Thanks and regards,
Three-stage least-squares regression
