Don't know about Stata as I don't have it here, but in SPSS:
count x = tag (1) .
crosstabs x by firm . <various options for %, stats>
What's the syntax in Stata?

Dear statalists,
I have a sample like the following,
firm tag
1 0
1 0
1 1
1 1
1 3
2 0
2 1
2 2
2 3
3 0
3 0
I want to generate a varialbe counting the number of "tag==1" in each level
of firm.
How to do it?
Thank you a lot!
Grace
