Breusch-pagan test hypothesis
WebBoth White’s test and the Breusch-Pagan are based on the residuals of the fitted model. For systems of equations, these tests are computed separately for the residuals of each … 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…

Did you know?
The Breusch–Godfrey test is a test for autocorrelation in the errors in a regression model. It makes use of the residuals from the model being considered in a regression analysis, and a test statistic is derived from these. The null hypothesis is that there is no serial correlation of any order up to p. Because the test is based on the idea of Lagrange multiplier testing, it is sometimes referred to as an LM test for serial correlation.

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. The Breusch-Pagan testis used to determine whether or not heteroscedasticity is present in a regression model. The test uses the following null and alternative hypotheses: 1. Null Hypothesis (H0):Homoscedasticity is present (the residuals are distributed with equal variance) 2. Alternative Hypothesis … See more Suppose we have the following dataset that contains information for 10 different basketball players: Using statistical software, we fit the following multiple linear regression model: rating = 62.47 + 1.12*(points) + … See more The following tutorials provide step-by-step examples of how to perform the Breusch-Pagan test in different statistical programs: How to Perform a Breusch-Pagan Test in Excel … See more
