WebThe Lags option includes autocovariance lags in the Newey-West estimator of the long-run variance. Therefore, the option does not affect the estimated OLS coefficients, standard errors, or MSE. Conduct a KPSS test for each lag from 0 through 4. Compare the standard OLS and the Newey-West estimates. Web22 jan. 2024 · Annual data = 1 lag, 2 lags. Quarterly data= 4 up to 8 lags. Monthly data = 12 up to 24 lags. Let’s dig into some formulas to understand the relationship between HAC … A Newey–West estimator is used in statistics and econometrics to provide an estimate of the covariance matrix of the parameters of a regression-type model where the standard assumptions of regression analysis do not apply. It was devised by Whitney K. Newey and Kenneth D. West in 1987, although there are a number of later variants. The estimator is used to try to overcome autocorrelation (also called serial correlation), and heteroskedasticity in the error terms in the mod… pre approved wards.com
