All of the following statements about Leave-One-Out Cross-Validation (LOOCV) are true, EXCEPT: O In each application of the training method, a single observation is used for the validation set. O the statistical learning method is fit on n-1 training observations. Since random sampling is used, a different estimate of test error is obtained each time LOOCV is used. O LOOCV can be computationally expensive to implement because one must fit the model n times 1 pts
