WebA simpler approach is to use robust methods for computing standard errors, such as Huber-White sandwich estimator. These produce correctly computed standard errors in the presence of heteroscedasticity; however, they do not correct for the actual model misspecification, so they may be more of a fig leaf than a real remedy. Webon the Huber’s formula (see section II). The Score and Hessian values for each observation are created right after the invoking of PROC LOGIST. The finite-sample adjustment in the procedure is based on Fuller’s method which takes into account the number of observations, the number of clusters and the number of independent variables. If ...
