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 [[alternative HTML version deleted]]
