Anything can happen as you add variables and interactions to a model.
My first question, though, is did you also add x when you added F?
When you add interactions the lower level terms used to create the
interactions should usually be in there as well.

Hi, Statalist,
I am confused about the interaction in gologit2.
in gologit2 model, if my raw model has independent variables
A,B,C,D. when i add interaction F=A*x, then in the new model ,the
sign of coefficient of A didn't change, but the sign of
coefficientsB , C or D changed. Does this imply that my model is
unstable, or have some problems?
thanks
