PooledMeanGroup (version 1.0)

BGtest: BGtest

Description

Tests autocorrelation between the current and lagged residuals. The test is a joint test of the first P autocorrelations

Usage

BGtest(residuals, explvariab, acor.ord)

Arguments

residuals

residuals for group i

explvariab

explanatory variables (regressors) for group i

acor.ord

order of tested autocorrelations

Value

Chi-squared and F statistics with probs

Details

Calculates statistics and probs of the Breusch-Godfrey autocorrelation test (with two variants: chi-squared and F
