WebUse the Breusch-Pagan test to assess homoscedasticity. The Breusch-Pagan test regresses the residuals on the fitted values or predictors and checks whether they can explain any of the residual variance. A small p-value, then, indicates that residual variance is non-constant (heteroscedastic). Run Breusch-Pagan test with estat hettest.
