Plot a Confidence Band Using HAC Estimates - MATLAB
WebIn the asset pricing literature, one typically adjusts for autocorrelation by using Whitney K. Newey and West ( 1987) t -statistics to test the null hypothesis that average portfolio excess returns are equal to zero. One necessary input for Newey-West standard errors is a chosen bandwidth based on the number of lags employed for the estimation. WebThe Newey-West method handles autocorrelation with lags up to h, and so it is assumed that lags larger than h can be ignored. Note too that Newey-West not only corrects for … shelves for sentry safe
