On the other hand, the Breusch-Godfrey test is based on the principles of the. Lagrange Multiplier testing. It is sometimes called as the LM test for serial correlation.

Il s'agit d'un test asymptotique qui teste directement la significativité du coefficient ρ dans la formule : Table of Contents Index EViews Help Lexikon Online ᐅBreusch-Godfrey-Autokorrelationstest: von Breusch und Godfrey (1979) vorgeschlagener Lagrange-Multiplier-Test zur Prüfung der Nullhypothese „keine Autokorrelation“ gegenüber der Alternativhypothese „Autokorrelation“ in großen Stichproben. The test is asymptotically equivalent to the Box- Pierce portmanteau test, or Q statistic (wntestq), for p lags, but unlike the Q statistic, the Breusch-Godfrey test is valid in the presence of stochastic regressors such as lagged values of the dependent variable. In statistics, the Breusch–Godfrey test is used to assess the validity of some of the modelling assumptions inherent in applying regression-like models to observed data series. In particular, it tests for the presence of serial correlation that has not been included in a proposed model structure and which, if present, would mean that incorrect conclusions would be drawn from other tests or N2 - We use Monte Carlo methods to study the properties of the bootstrap Breusch-Godfrey test for autocorrelated errors in two versions a) by bootstrapping under the null hypothesis, restricted and b) by bootstrapping under the alternative hypothesis, unrestricted. We use the residual bootstrap for the bootstrap-BG test. I know the White test tests for nonlinear forms of heteroskedasticity.

In order to perform a BG test, the simple regression model is first fitted by ordinary least squares to obtain a set of sample residuals. Then the residuals are used the as the dependent variable and regressed over independent variables and its first p-lags.

Durbin‐Watson statistic or use some other tests of autocorrelation such as the Breusch‐Godfrey (BG) test How can you remedy the problem? Consider possible model re‐specification of the model: a different functional form, missing variables, lags etc.

Whereas the Durbin-Watson Test is restricted to detecting first-order autoregression, the Breusch-Godfrey (BG) Test can detect autocorrelation up to any predesignated order p. It also supports a broader class of regressors (e.g.
