We covered Ch. 10-4 Prediction Intervals and Variation (Prediction intervals, total deviation, explained deviation, unexplained deviation, coefficient of determination, and the Turing Test for Artificial Intelligence.), 10-5 Multiple Regression (Multiple variation, multiple regression, multiple coefficient of determination, adjusted coefficient of determination.), 11-1 Introduction, and 11-2 Goodness of Fit (Hypothesis test, expected frequency). We also discussed the real-world application of statistics and algorithms to electronic game design.
