You probably could use -sureg- that way but it is not the most direct
approach. 

Have a look at -help epitab-, in particular -help mhodds-.

If you want to stay within the % metric and frame your problem in a
regression context you can use -betafit- or the fractional logit (-glm-
with the -family(binomial)- and -robust- options. For both -betafit-
and the fractional logit see:

Hope this helps,
Maarten
