Use to fit a least squares regression line to a scatterplot or matrix plot. Use the regression fit to examine the relationship between the response variable (y) and the predictor variable (x). If you hover the mouse pointer over the fitted line, Minitab displays the fitted regression equation. After creating a graph, you can:

·    Change the model order for the regression fit, add groups, or change the fitted line attributes (see Editing Data Fits Overview).

·    Add a regression fit (see Adding Graph Elements).

Dialog box items

Model Order

None: Choose to suppress the regression fit.

Linear: Choose to fit a linear model.

Quadratic: Choose to fit a quadratic model.

Cubic: Choose to fit a cubic model.

Fit intercept: Check to fit a constant term (the y-intercept of the regression line). Uncheck to fit the model without a constant term.
