st: generating predicted probabilities, setting variables constant at mean or mode

Hi Statalist,
I am graphing some predicted probabilities from a Generalized Ordered
Logistic Regression model. I am using Long & Freese's SPost commands
(i.e. prgen and praccum) and Williams' gologit2 (in Stata IC 11.2). My
model has both categorical and continuous predictors.
When I run praccum, I use the x() option to assign specific values to
some variables and then I use rest(mean) to set other variables
constant at their mean. Rest(mean) obviously makes sense for
continuous predictors, but it isn't intuitive for categorical
variables. I can't find SPost examples where, after specifying x(),
users set categorical predictors constant at their mode.
Could someone provide insight into why I would set categorical
predictors constant at their mean and not their mode?
Thanks,
Sara
