If the idvariable is not unique, it is assumed that it identifies clusters of correlated observations. The robust estimate arises from many different arguments and thus has had many labels. It is variously known as the Huber sandwich estimator, White's estimate (linear models/econometrics),

WebThe cluster term is used to compute a robust variance for the model. The term + cluster (id) where each value of id is unique is equivalent to specifying the robust=TRUE argument.
