Dear statalister:

I have 4 subpopulation (group A (n=200), B(n=200), C(n=200), D(n=400))

I need to create a new categorical variable, this variables is the 4Q-tile of variable varXXX but the distribution of the quartile is according to subpopulation D.

I use the xtile & the xtile2 command, but I not sure than the new 4Q variable is ok.


xtile2 var4Q=varXXX , nq(4) by(grupD)

but grupD have 600 missing and the new variable var4Q have 400 observations and not 1000.

Can You help me?
