White Adjusted Standard Error


Loading... The question is close related to the question how to deal with outliers. When the assumptions of E [ u u ′ ] = σ 2 I n {\displaystyle E[uu']=\sigma ^{2}I_{n}} are violated, the OLS estimator loses its desirable properties. Not the answer you're looking for?

Robust Standard Errors Stata

MacKinnon, James G.; White, Halbert (1985). "Some Heteroskedastic-Consistent Covariance Matrix Estimators with Improved Finite Sample Properties". Woolridge says that when using robust standard errors, the t-statistics obtained only have distributions which are similar to the exact t-distributions if the sample size is large. Why can't the second fundamental theorem of calculus be proved in just two lines? MR0216620.

Here R1 is an n × k  array containing the X sample data and R2 is an n × 1 array containing the Y sample data. Worse yet the standard errors will be biased and inconsistent. The standard standard errors using OLS (without robust standard errors) along with the corresponding p-values have also been manually added to the figure in range P16:Q20 so that you can compare this content H.
