发帖数: 70 | 1 In my regression model, I have one variable (A) with four levels, and one
variable (B) with two level.
I detected an interaction between these two variables. But only fourth level
of variable A with variable B.
How should I write code in SAS for proc logistic, that only include the
interaction between (level 4 of A) and B? | w*******9

indicators by sas |
