Godfrey's test
WebO teste tem o nome de Trevor S. Breusch e Leslie G. Godfrey . Plano de fundo [ editar ] O teste de Breusch – Godfrey é um teste de autocorrelação dos erros em um modelo de regressão. Ele faz uso dos resíduos do modelo que está sendo considerado em uma análise de regressão e uma estatística de teste é derivada deles. WebThis is the basis of the Breusch–Pagan test. It is a chi-squared test: the test statistic is distributed nχ2with kdegrees of freedom. If the test statistic has a p-value below an appropriate threshold (e.g. p < 0.05) then the null hypothesis of homoskedasticity is rejected and heteroskedasticity assumed.

WebBreuschGodfreyTest performs the Breusch-Godfrey test for higher-order serial correlation. Usage BreuschGodfreyTest (formula, order = 1, order.by = NULL, type = c ("Chisq", "F"), data = list (), fill = 0) Arguments Details Under H_0 H 0 the test statistic is asymptotically Chi-squared with degrees of freedom as given in parameter . WebIn statistics, the Durbin–Watson statistic is a test statistic used to detect the presence of autocorrelation at lag 1 in the residuals (prediction errors) from a regression analysis.It is named after James Durbin and Geoffrey Watson.The small sample distribution of this ratio was derived by John von Neumann (von Neumann, 1941).

The Ljung-Box … WebThe GODFREY= option in the FIT statement produces the Godfrey Lagrange multiplier test for serially correlated residuals for each equation (Godfrey, 1978a, 1978b ). n is the maximum autoregressive order, and specifies that Godfrey’s tests be computed for lags 1 through n. The default number of lags is four.
WebThe 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. [3] WebApr 1, 2024 · Thankfully, Godfrey’s attacks are fairly predictable.
