Abstract
The Bahadur type representation of linear combination of order statistics with possibly discontinuous weight function J is established. The order of the remainder term depends on the smoothness of J. An analogous representation up to Op(n-1) is derived for a Studentized estimator. The representations are incorporated into the study of asymptotic relations of L- and M-estimators which could be equivalent up to the order Op(n-1) under some conditions.
