Dear statalist community, Someone may please offer help, in a stata command for studying the interaction.



In my logit regression, I have an interaction term :

i.Teacher_group # i.Student_group # c.Semester

How interaction of Teacher_group and Student_group statistically affect DepVar, as the student moves up the Semester?

Teacher_group has 4 levels
Student_group has 4 levels
Semester -- semester 1 to 5th

regards
ajay

Ajay:
it is difficult to reply without seeing what you typed and what Stata gave you back (as per FAQ).
That said:
1) why considering -semester- as a continuous variable?
2) in the meantime, the -allbaselevels- option can be helpful.

thanks, Carlo for your valuable guidance. I could figure that out by treating semester as a fixed effect.
