Dear Statalisters:
I would like to test the equality of proportions of two variables which are not binary. Each variable can have four values (0, 1, 2 and 3). (To be more precise, the original variable is the same but are applied to two different populations, the total sample and a restricted sample. I created two different variables. With -tabulate-, I get easily the frequencies of both variables).
I can't use -prtest- and -ztest- because these two commands require, to my knowledge, binary variables.
My comparison should work on unpaired data.
I searched in Stata on "proportions" but did not find any command for that purpose. I missed maybe something. Would you have an idea?
Best regards
Herv� Stolowy
