WebIn statistics, a regression equation (or function) is linear when it is linear in the parameters. While the equation must be linear in the parameters, you can transform the predictor variables in ways that produce curvature. For instance, you can include a squared variable to produce a U-shaped curve. Y = b o + b 1 X 1 + b 2 X 12. Web1 day ago · and the graph looks like below. Now in location C, it does not show the linearity. So I want to not show the regression line (or provide different color or dotted line, etc.,) in only location C. Could you let me know how to change regression line type per group? Always many thanks!!
