Multiple regression
- Maybe you're wondering how a vehicle's speed and driver reaction time affects stopping distance, or maybe you're curious if there is a relationship between height and weight and how gender might affect it. These are questions where there are multiple variables, or Xs, that possibly affect an outcome or response Y. Multiple regressions need to be run to analyze these possible relationships and develop a valid model to predict future performance. Let's get started on multiple regression using Minitab. To get started, download from the exercise files the worksheet MultipleRegressionData.mtw, and open it. Let's deal with the first three columns first. We have the Y being the Stopping Distance, and the potential Xs would be the Speed and Driver Reaction Time. Let's do a regression. Go up to Stat menu, Regression, Regression, and Fit Regression Model. The Response is Stopping Distance, and the predictors are Speed and Driver Reaction Time, both of which are Continuous. We do not have any…
