HI,I am analyzing a risk model for type 2 diabetes using a logistic regression.
In the final model I have only 6 predictors. The regression gives correct
output (fullmod is the fitted model). Now I try to do cross validation using
cv.binary. Any help in resolving this problem will be appreciated.
> cv.binary(fullmod)
Error in sample.int(x, size, replace, prob) : invalid 'size' argument
Regards,Amit
