Anyone can guide me how can I do the heteroscedasticity test, I don’t want to use the Proc Reg procedure as, I already have the model.
I have the model suppose Y = 1.2 + 0.25 * X. By running this model I can generate the expected Y series and comparing it to actual Y; which can give me the Residuals.
So I have these residuals and based on this I want to do the heteroscedasticity test.
