Is there some way to use the -xi- command with multiple variables? This
is the context of a three level nested logit model with around 10
independent variables. I need to create interactions for all of the
nests.
I have a categorical variable that I want to interact with a number of
continuous variables, is there a Stata command to do this? Xi only
seems to work with one variable.
Let variable categorical_1-categorical_3 have 5 levels each.
Let var1-var8 be continuous variables that I want to interact them with.
Is there some way to interact categorical_1*(var1-var8),
categorical_2*(var1-var8), and categorical_3*(var1-var8) easily? I know
I can change the prefix, but this still requires 24 different prefixes
and creates a number of redundant dummies. Surely this must be a common
task and I'm overlooking something.
Thanks for any help you can give.
