Hi David
My data set has about 20 significant variables and step function with logistic
regression is working fine( in R-commander). I tried to get conditional
logistic by introducing the stratum variable and clogit. The clogit is not
converging but is giving the summary of the model. When step/step AIC/..are
used, the message given is "ERROR: number of rows in use has changed".
Thanks
Subha
