Problem 8 (16 pts). Assume you are provided with a dataset containing 5 observations and three features to use in creating a regression model. The table below contains information for two different proposed models, with each row relating to a different model. The first four columns provide the proposed coefficient estimates for each model. Columns 5 - 9 contain the predicted y values resulting from each of the models. The true y values are provided in the bottom row of the table. For both of the proposed models, calculate its loss using the linear regression loss function, the ridge regression loss function with a = 0.5, and the LASSO regression loss function with a = 0.5. In each case, use SSE rather than MSE as the "baseli ne" loss. After calculating each of the loss values, circle the best loss for each of the three different loss functions. In other words, for each of the last three columns, circle the best loss value that appears in that specific column .
