Analysis of Variance with two Factors,generalize this approach to problems with three or more factors. Indeed, regression analysis can be used to obtain the results for any type of anova problem, albeit the results will be tedious to sort out.

Our goal in writing this casebook and the companion volume (Basic Business Statistics) was to change that impression by showing how statistics gives insights and answers interesting business questions.

In addition, similar intervals known as prediction intervals provide estimates of the accuracy of predictions from the fitted model.
