regression - Optimal Lag for Newey West - Cross Validated

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… Web2 mei 2014 · You can also still do Newey-West in pandas ... 1.4280 intercept 2.0576 2.9413 0.70 0.5019 -3.7073 7.8226 *** The calculations are Newey-West adjusted with lags 1 -----End of Summary----- Share.
