Asking for robust standard errors does not amount to robust regression in the sense just discussed, ...
Web19 apr. 2015 · Using the Huber-White sandwich errors would also be good. Here are some answers to your specific questions: Robust regression is a viable option, but would be better if paired with weights in my opinion. If you aren't worried that the heteroscedasticity is due to outliers, you could just use regular linear regression with weights. Web16 nov. 2024 · Robust variances give accurate assessments of the sample-to-sample variability of the parameter estimates even when the model is misspecified. The robust variance comes under various names and within Stata is known as the Huber/White/sandwich estimate of variance. The names Huber and White refer to the …
Webthe robust (Eicker-Huber-White, or EHW, and Liang-Zeger or LZ, from hereon) variance estimators are biased downward, and the normal-distribution-based confidence intervals using these variance estimators can have coverage substantially below nominal coverage rates. There is a large literature documenting and addressing these small sample problems Web30 jan. 2024 · The bottom of page 426 states that weighted least squares uses the modified variance for the mean response confidence intervals, but page 427 seems to imply that White's estimator is only used for coefficient std errors. I may not be connecting things through. I will post some code above which may help. $\endgroup$ –

WebThe robust variance estimator goes by many names: Huber/White/sandwich are typically used in the context of robustness against heteroskedasticity. Survey statisticians often refer to this variance calculation as a first-order Taylor-series linearization method.
