Loo leaveoneout

WebLeave One Out (LOO)¶ LeaveOneOut (or LOO) is a simple cross-validation. Each learning set is created by taking all the samples except one, the test set being the sample left out. Thus, for \(n\) samples, we have \(n\) different training sets and \(n\) different tests set. http://mc-stan.org/loo/articles/loo2-large-data.html
