Hello,
I am using a Proportional Hazard Model with time-dependent variables like
diabetes duration. Can I get a coef with an opposite (negative) direction
-contrary to what I expected- if I am using time-dependent variables? Why the
coef for the same variable is positive if I am using Exponential Regression?
Thank you,
Aida
