Statistics 528 - Lecture 10 1 Statistics 528 - Lecture 10 Prof. Kate Calder 1 Regression Using MINITAB Example: Poplar tree example (from lecture 1) - poplar2.mtw We are interested in whether D 2 H can be used to predict the weight of trees. Regression of Weight on D 2 H : Weight = a + bD 2 H Select Stat-Regression-Regression Response: Weight Predictors: D 2 H Output: regression equation, r 2 , possible outliers and influential observations Statistics 528 - Lecture 10 Prof. Kate Calder 2 Residuals and Fitted Values: Select Stat-Regression-Regression and click on Storage . Select Residuals and Fits. Residual Plots: 1. Use the residuals and fitted values in the worksheet to make them. 2. Select Stat-Regression-Regression and click on Graphs .
