How do you test for linearity
WebJun 5, 2024 · Linearity: The expected value of the dependent variable is a linear function of each independent variable, holding the others fixed (note this does not restrict you to use a nonlinear transformation of the independent variables i.e. you can still model f(x) = ax² + bx + c, using both x² and x as predicting variables.
