WebFeb 26, 2015 · In my real example, the data is highly autocorrelated, hence the importance of doing HAC adjustment. Now, here is a simple example (note that Y here is not autocorrelated): Y = rand (500,1); X = ones (500, 1); hac (X, Y, 'intercept', false, 'weights','BT','display','full') However, when I compare the results to simple OLS … WebSpecifying wmatrix(hac kernel) requests an HAC weighting matrix using the speciﬁed kernel and N 2 lags, where Nis the sample size.

WebIn Stata, the command newey produces Newey–West standard errors for coefficients estimated by OLS regression. In MATLAB, the command hac in the Econometrics toolbox produces the Newey–West estimator (among others). In Python, the statsmodels module includes functions for the covariance matrix using Newey-West. Web10. I found an R function that does exactly what you are looking for. It gives you robust standard errors without having to do additional calculations. You run summary () on an lm.object and if you set the parameter robust=T it gives you back Stata-like heteroscedasticity consistent standard errors.

A basic property of variances and matrices is that. v a r [ A T Y] = A T v a r [ Y] A. So. v a r [ β ^] = ( X T X) − 1 X T v a r [ Y] X ( X T X) − 1. It's usual when considering HAC estimators to break this into three pieces, two of which are the same, hence the name "sandwich".
