The goal is to fit the best multiple regression model to the response (infection risk).
Do an analysis using the first 108 observations.
Use the stepwise regression method to see which model is the best. Repeat using subset regression.
Do they agree?
Are there any outliers in the data?
Look for x-outliers, y-outliers, and high-influence points.
Come up with one model that you think best describes the data and can be used for future predictions.
Show the residual plot for this one. Does the model seem appropriate?
Use this model to predict (using prediction interval) y for the last 5 observations of the data and see if the model is doing well.
