Extensions of the concept of local ancillarity
Department of Mathematics, Imperial College London
Cox (1980) introduced a notion of local ancillarity. In this paper, a qth order local ancillary variable is defined; the idea of local ancillarity for the multiparameter model with no nuisance parameters is developed for inference and third-order local ancillarity is examined in the single parameter model.
