10.2.2 Non-Constant Variance. A second thing to look for in visual diagnostics of residuals is non-constant variance, or heteroscedasticity.In this case, the variation in the residuals over the range of predicted values for \(Y\) should be roughly even.

Since our model will usually contain a constant term, one of the columns in the X matrix will contain only ones. This column should be treated exactly the same as any other column in the X matrix.To calculate the F-test of overall significance, your statistical software just needs to include the proper terms in the two models that it compares. The overall F-test compares the model that you specify to the model with no independent variables. This type of model is also known as an intercept-only model.
