Hi,

I'm interested in finding out if STATA has the capability of running a
power calculation for two categorical variables with more than 2 levels
each. 

Here would be a sample 2X4 table, and we want to determine the sample
size necessary to detect differences in proportions across a
multiple-category variable. Does anyone have any suggestions for code
within STATA?
