Use Fitted Line Plot to display the relationship between one continuous predictor and a response. You can fit a linear, quadratic, or cubic model to the data. A fitted line plot shows a scatterplot of the data with a regression line representing the regression equation.
For example, an engineer at a manufacturing site wants to examine the relationship between energy consumption and the setting of a machine used in the manufacturing process. The engineer thinks the relationship between these variables is curvilinear. Therefore, the engineer created a fitted line plot and fits a quadratic model to the data.
To create a fitted line plot, choose .
