WebBreusch-Pagan Lagrange Multiplier test for heteroscedasticity. The tests the hypothesis that the residual variance does not depend on the variables in x in the form. Homoscedasticity implies that \(\alpha=0\). Parameters: resid array_like. For the Breusch-Pagan test, this should be the residual of a regression. If an array is given in exog ... Web2.2.5 Breusch – Pegan – Godfrey Test As the last step in our testing procedure, we apply the Breusch-Pegan-Godfrey test. We test the null hypothesis that the residuals are homoscedastic against the alternative hypothesis being the residuals are heteroskedastic (see, Breusch & Pagan, 1979). To do so, we fit the following equation: y b b x b z e
