Hello,
I have analyzed my dataset as a case-control study (via logistic 
regression), and I am now interested in analyzing it as a case-cohort 
study.  The only help I could find online or in the help section 
suggests analyzing my data as survival time analysis which I do not 
want to do.  Please tell me how it is possible to set my data so that 
it can be analyzed as a case-cohort design, via logistic regression.  
The problem I am having is that in order to use the entire population  
(including cases) as my controls I need to define a case-control 
variable that equals 1 for case and 0 for control, but all cases are 
also controls. Thus, defining such a variable seems impossible.

Thank you,
Jonathan Golub
