Hi, everyone:
I am running logistic regression on a bunch of variables using apply
command. But an error occurs, the whole process stops. I am wondering
if anyone knows how to skip this error and to continue the
regression for the rest of variable.
What I did is that first confine a function to the logistic
regression, then use
apply(data, 2, reg.fun)
Then I got an error which is
[1] "The result of logistic regression:"
Error in `contrasts<-`(`*tmp*`, value = "contr.treatment") :
contrasts can be applied only to factors with 2 or more levels
Can anyone help me out? Thanks a lot.
Suyan
