I have run an interaction effect using logistic GEE on PROC GENMOD. I’ve used the following SAS codes to run this analysis:-
PROC GENMOD DATA=my_filename descending;
CLASS obs_number company_id;
model completed = CAR*CEO_Pay
Year1993 Year1994 Year1995 Year1996 Year1997
REPEATED subject=company_id /TYPE=ar(1) CORRW covb ;
Both CAR and CEO_Pay are continuous independent variables.
The dependent variable “completed” is a binary coded variable (completed acquisition=1, abandoned acquisition=0).
Covariate1 is a continuous control variable.
Covariate2 is a binary control variable.
I need to graph the interaction between CAR and CEO_Pay (CAR*CEO_Pay) but I’m struggling to determine the correct SAS codes for graphing this interaction. I have read up many SAS articles but have not found something that meets my needs.
I would really appreciate if you’d please point me in the right direction by providing a sample SAS code to graph the above interaction as well as any sources/literature that deals with this issue. I am using SAS 9.3.
Thank you in advance for your assistance!
