Linear Regression
The following labs are from James, Witten, Hastie, and Tibshirani’s An Introduction to Statistical Learning, pp. 109-115. This short tutorial goes through univariate and multivariate linear regression, i.e., with one response variable and one or multiple predictor variables, respectively. It also includes an example of interaction terms, where predictor variables are multiplied and essentially play the role of another single variable.
Physical Activity Measured by Steps
Measurements taken over two months, as number of steps taken in all 5-minute intervals.
