Cross Validation

The Validation Set Approach

split a dataset into fixed amount of training dataset and testing dataset

K-Fold CV

k-fold cv involves randomly dividing the set of observations into k groups of approximately equal size.

Leave-One-Out Cross-Validation (LOOCV)

loocv involes spliting the set of observations into two parts. However, instead of creating two subsets of comparable size, a single observation (x, y) is used for the validation set, and the training observation make up the training set.
