GLMNET warning msg
It means that 10/10 = 1 < 3. It also means that what you're trying to do (fitting 10 cases to 12000 variables) is ridiculous (assuming I understand your message correctly). Cheers, Bert

Hi I'm getting the following warning msg after ?cv.glmnet and I'm wondering what it means...
dim(x) 10 12000;
dim(y) 10; #two groups case=1 and control=0
cv.glmnet(x, y)
Warning message:
Option grouped=FALSE enforced in cv.glmnet, since < 3 observations per fold
Thanks,
