Let's say I have a model with 30 potential covariates. How many potential variants on the models can I have? What does this imply about the tradeoff between forward/backward selection over best subset selection. (0.5 pts) If the underlying data is highly linear, we would expect QDA to outperform LDA. True or False? (0.5 pts) We have a dataset of genetics sequencing outcome, with 30 observations and 4000 variables. You are trying to determine the best method for regression analysis. Colleague A is advocat- ing for KNN, Colleague B is advocating for linear regression, Colleague C thinks Colleague A and B are both wrong. Who should you side with? (1 pt)
