Fitted Line Plot Stat > Regression > Fitted Line Plot
This procedure performs regression with linear and polynomial (second or third order) terms, if requested, of a single predictor variable and plots a regression line through the data, on the actual or log10 scale. Polynomial regression is one method for modeling curvature in the relationship between a response variable (Y) and a predictor variable (X) by extending the simple linear regression model to include X2 and X3 as predictors.
Response [Y]: Select the column containing the Y, or response variable.
Predictor [X]: Select the column containing the X, or predictor variable.
Type of Regression Model
Linear: Choose to fit a linear regression model.
Quadratic: Choose to fit a quadratic model.
Cubic: Choose to fit a cubic model.
