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… WebThe most well-known test for detecting unobserved heterogeneity is due to Breusch and Pagan (1980, BP test hereafter). Although the BP test was originally developed to deal with both individual and time effects, the version of the BP test to detect only the individual effects seems to have received the most attention. Such a version of the BP test
