st: Nonparametric test

[nigussie Tefera <nitefera@yahoo.com>]

Dear all
I have two categorical variables: namely incomecat (1=high,2=middle and 3=low income) and country ( labeled as (x, y, z, w)). Suppose that each country has high, middle and low income group. If I want to run paired test for each income group across countries, what stata command� should I use?
