" and for the Group, it is not uniform at 5, it is from 1 to
7."


Are the ids within the wards contiguous, i.e. 1,2,3,4? If not, the -assert-
line in Austin`s code will stop Stata.

Austin,
Thanks for your reply. Yes, i would like to have something like that.

But, its turn out the actual data is more complicated than the hypothetical
I made before.
I have 74 wards. and for the Group, it is not uniform at 5, it is from 1 to
7.

So?

Best regards,
Kartika
