"NettetLeave-one-out cross-validation (LOOCV) is closely related to the validation set approach as it involves splitting the set of observations into two parts. However, instead of creating two subsets of comparable size (i.e. 60% training, 40% validation), a single observation ( ) is used for the validation set, and the remaining observations { } make up the training set.
