WebMar 20, 2024 · One test that we can use to determine if heteroscedasticity is present is the Breusch-Pagan Test. This test produces a Chi-Square test statistic and a corresponding p-value. If the p-value is below a certain threshold (common choices are 0.01, 0.05, and 0.10) then there is sufficient evidence to say that heteroscedasticity is present.
