In the "spost" pakage by Long & Freese, the command "prchange" enables us to
measure the effect of discrete changes of the explanatory variables.
I have a question regarding this command:
Suppose I want to estimate a multinomial logit model, with "age" as a
dependant variable, which ranges from 20 to 60. The "prchange" command will
give me the effect on the categorial variable when "age" varies from 20 to
60 (If I got that right!).
Is there a way to obtain this effect for different variations of the
variable? i.e if age varies from 20 to 40 and then from 40 to 60? I didn't
find the answer in the help file...
