Ex 7: testing for Heteroskedasticity
Multiple R squared is .45 yet when they run the Breusch Pagan Test it comes out to 0.193
Hi Alex, for BP test you use different R-squared (will be given in the exam), not the multiple-R-squared.
It’s still a multiple-r-squared. It’s just from a different regression-- one of the squared residuals of the original model on all of the independent variables in the model.
