[R] conditional logistic regression

[Eman Alissa]

Hi all

I've got a case-control study, matched for age 1:1. I
need to run a conditional logistic regression using
SPSS version (11.5). I was told that it can be
performed using cox regression model. However, I can
not figure where the independent variables (numeric
and categoric) should go? what do strata variable and
the model time mean?!
Can someone please clarify how to fill the options of
the dialogue box?
Thanks a million
