In statistics, the Breusch–Godfrey test, named after Trevor S. Breusch and Leslie G. Godfrey, is used to assess the validity of some of the modelling assumptions inherent in applying regression-like models to observed data series.

Breusch-Godfrey Test. Auxiliary regression of residuals on lag. Test statistic: Critical value: (e.g., at 5% significance, c.v. = 3.84) Can add more lags to auxiliary regression. critical value: e e X X u.

econometric tests assumption errors are normally distributed test assumption expected value of the errors is zero. on errors, ho: Breusch-Godfrey test.

Tto assess the serial correlation, Breusch Godfrey serial correlation test will be used. This test assumes about the independence of the disturbances from observation to observation.

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.

There is the problem of autocorrelation exists, if this assumption is violated the errors in one time period are correlated with their own values in other period.

The Ljung-Box test is based on second moments of the residuals of a stationary process (and thus of a comparatively more ad-hoc nature).

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.

The GODFREY= option in the FIT statement produces the Godfrey Lagrange multiplier test for serially correlated residuals for each equation (Godfrey 1978a and 1978b). is the maximum autoregressive order, and specifies that Godfrey’s tests be computed for lags 1 through . The default number of lags is four.

t t 2020-11-03 Breusch-Pagan Test There is another procedure that uses a rather easy statistic that is also depen-dent on the goodness of ﬂt measure, call the (LM) Lagrange Multiplier statistic. This test based using the LM statistic is known as the Breusch-Pagan Test for Heteroskedasticity.

This test uses the following hypotheses: H 0 (null hypothesis): There is no autocorrelation at any order less than or equal to p. Breusch-Godfrey Test . STATA NOTES: To demonstrate that replacing the missing value of . e. ˆ.
