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. latin mass west palm beach fl

WebThis heteroscedastiicity test has been developed by Breusch and Pagan (1979), and later improved by Koenker (1981) - which is why this test is sometimes named the Breusch- Pagan and Koenker test - to allow identifying cases of heteroscedasticity, which make the classical estimators of the parameters of the linear regression unreliable. ...

WebJan 1, 1988 · Introduction Breusch and Pagan (1979) developed a simple test for a broad class of heteroscedastic specification of disturbances in a linear regression model.

WebThe idea behind the Pagan–Hall test is that if any of the exogenous variables can pre-dict the squared residuals, then the errors are conditionally heteroskedastic. The more common Breusch–Pagan and White tests for heteroskedasticity (Breusch and Pagan 1979; White 1980) are inappropriate here because, as Pagan and Hall (1983) point out,
