WebI have discovered some heteroscedasticity in my model that I would like to compensate for with more robust standard errors. I have tried to use the Huber-White robust standard … WebThis same approach is used in Huber-White’s Robust Standard Errors method where there isn’t homogeneity of variances, except that S is calculated in a different way. The Newey-West method uses the same approach, except that XTSX is calculated in yet another way.

WebHuber-White standard errors assume is diagonal but that the diagonal value varies, while other types of standard errors (e.g. Newey–West, Moulton SEs, Conley spatial SEs) make other restrictions on the form of this matrix to reduce the number of parameters that the practitioner needs to estimate. st. george church framingham maThe first such approach was proposed by Huber (1967), and further improved procedures have been produced since for cross-sectional data, time-series data and GARCH estimation.
