Greetings Statalisters -
If I have a categorical variable where the values do not assume
any sort of natural ordering (i.e. nominal) and I'd like to use
that variable in a regression analysis (e.g. logistic) with one
value of the variable serving as the referent - how best to
achieve?? If I use the - xi: - command, I obtain a series of
dichotomous variables useful in examining the effect that value
has relative to all others within that variable, but not
necessarily relative to my arbitrary referent group. I
recognize that I could create a series of dichotomous variables
using the -gen- command, but it seems there may be an
alternative way. Any input is appreciated.
Thanks,
Clint Thompson
