RecursiveLSResults.test_normality(method)

Test for normality of standardized residuals.

Null hypothesis is normality.

Parameters

methodstring {‘jarquebera’} or None

The statistical test for normality. Must be ‘jarquebera’ for Jarque-Bera normality test. If None, an attempt is made to select an appropriate test.

Notes

Let d = max(loglikelihood_burn, nobs_diffuse); this test is calculated ignoring the first d residuals.

In the case of missing data, the maintained hypothesis is that the data are missing completely at random. This test is then run on the standardized residuals excluding those corresponding to missing observations.
