Robust Standard Errors Stata RRegCoeff(R1, R2, hc, con) = kk × 2 range consisting of the regression coefficient vector followed by vector of standard errors of these coefficients, where kk = k+1 if con = TRUE (default) Techniqually what happens is, that the variances get weighted by weights that you can not prove in reality. http://www.real-statistics.com/multiple-regression/robust-standard-errors/ The question is close related to the question how to deal with outliers.

Robust Standard Errors In R When the model is correctly specified and the errors are independent of the regressors, the rejection of this null hypothesis is evidence of heteroscedasticity. These estimates are BLUE (best linear unbiased estimate), but only for large samples.
