Exercise 2. Consider the iris data set. (a) Fit a linear regression model for Sepal.Width using Sepal.Length and Species as predictors. Recall that Species is a categorical variable with 3 levels (setosa versicolor, and virginica). Use summary) to print the results. What is the base- line level for Species in the model? (b) Fit a linear regression model for Sepal.Width using Sepal.Length, Species, and the interaction between Sepal.Length and Species as predictors. Use summary ) to print the results. (c)...

A University is applying Classification methods in order to ldentity alumini who may be interested in donating money. The University has a database of 58,205 alumni profiles containing numerous variables. Of these 58,205 alumni, only 576 have donated in the past. The university has oversampled the data and trained a random forest of 100 classification trees. For a cutoff value of 0.5, the following confusion matrix summarizes the performance of the random forest on a validation set: Predicted Actual Donation...
