in this case you have to use the -gen- instead of the -egen- command.

2006/8/2, irodriguez <[email protected]>:
I have a panel data for 1200 firms by year (10 years for each firm)
I need to create a lagged variable of one called  roa but it must be lagged
for each firm
I tried with
by empresa: egen lagroa= roa[_n-1]
but the command give me this error: r(198)
What can I do?
Thanks
