(a) Next fit the estimators of varying complexity, i.e., g1, g2, ....g15 using the training set for each dataset. Then calculate and plot the squared bias, variance, and error on the testing set for each of the estimators showing the tradeoff between bias and variance with model complexity. (8) (Note: You will have one plot, where the x-axis will be model complexity in polynomial degree, i.e. from 1 to 15. You will plot three lines: Squared bias, variance, and error, all calculated on the testing set only)
