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 : WebThe Stata option ( not command) robust implements robust (Huber-White-sandwich) standard errors that are offered as more honest standard errors in the face, principally, of heteroscedasticity.
