A useful mathematical illustration comes from the case of one-way clustering in an ordinary least squares (OLS) model. Consider a simple model with N observations that are subdivided in C clusters. Let be an vector of outcomes, a matrix of covariates, an vector of unknown parameters, and an vector of unexplained residuals: As is standard with OLS models, we minimize the sum of squared residuals to get an estimate : WebHuber-White (Robust) Sandwich Estimator Ronald Christensen Department of Mathematics and Statistics University of New Mexico May 22, 2015 Abstract KEY WORDS: 0.

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. Web28 okt. 2014 · AIT Worldwide Logistics.
