In Step 2 of XL Miner's k-Nearest Neighbors Classification procedure, be sure to Normalize Input Data, Score on best k between 1 and specified value, and assign prior class probabilities According to relative occurrences in training data. A. For k = 1, what is the overall error rate on the training set and the validation set, respectively? Explain the differ.
