WebThe \(t_{23}\) probability area to the left of 1.31648 is 0.8995, which means the p-value for the test is \(2(1-0.8995) = 0.201\), i.e., there is no evidence the errors have nonconstant variance. Breusch-Pagan Test. The Breusch-Pagan test (also known as the Cook-Weisberg score test) is an alternative to In statistics, the Breusch–Pagan test, developed in 1979 by Trevor Breusch and Adrian Pagan, is used to test for heteroskedasticity in a linear regression model. It was independently suggested with some extension by R. Dennis Cook and Sanford Weisberg in 1983 (Cook–Weisberg test). Derived from the Lagrange multiplier test principle, it tests whether the variance of the errors from a regression is dependent on the values of the independent variables. In that case, heteroskedast…
