Witryna1 Answer. This [the LM statistics] follows a chi-squared distribution, with degrees of freedom equal to the number of estimated parameters (in the auxiliary regression) minus one. A rapid inspection of the original article of White (1980) confirms this (eq. 2, eq. 3, and Corollary 1 in the article should be what you are looking for).

In statistics, the White test is a statistical test that establishes whether the variance of the errors in a regression model is constant: that is for homoskedasticity. This test, and an estimator for heteroscedasticity-consistent standard errors, were proposed by Halbert White in 1980. These methods have … Zobacz więcej To test for constant variance one undertakes an auxiliary regression analysis: this regresses the squared residuals from the original regression model onto a set of regressors that contain the original … Zobacz więcej • Gujarati, Damodar N.; Porter, Dawn C.
