This paper discusses the validity of using common random numbers (CRNs) with two-stage selection procedures to improve the possibility of correct selection and discusses the intrinsic subset pre-selection of the Enhanced Two-Stage Selection (ETSS) procedure. We propose using CRNs with Rinott's two-stage selection and ETSS procedures when the underlying processes satisfy certain conditions. An experimental performance evaluation demonstrates the improvement in the possibility of correct selection of using CRNs with two-stage selection procedures and the intrinsic subset pre-selection of the ETSS procedure.
