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.
