Dear R user,
I am working with LOO. Can any one who is working
with leave one out cross validation (LOO) could send me the code?
Thanks in advance

I don't think that LOO adequately penalizes for model uncertainty. I
recommend the bootstrap or 50 repeats of 10-fold cross-validation. See
for example the validate and calibrate functions in the R Design package.
