Websquares (FGLS) rather than ordinary least squares (OLS). Examples include random effects estimators and, more generally, random coefficient and hierarchical models. If all goes well this provides valid statistical inference, as well as estimates of the parameters of the original regression model that are more efficient than OLS.
