Repeated time values within panel

[Dario Maimone Ansaldo Patti]

Dear All,

I am dealing with a panel of firms. When I type:

xtset id year

I get:

. xtset id year
repeated time values within panel
r(451)

I know the procedure to identify the repeated values (for instance the one reported at this link: http://www.stata.com/support/faqs/da...d-time-values/)

Now, suppose that I do not mind which of the two (or more) repeated values I drop, as far as I have only one entry for each id in each year.

Do you have any suggestion about how I can drop the repeated values quickly instead of doing it manually?

Thanks in advance.

use the -duplicates- command; you may need to use the "force" option so read the help file carefully
