On the Ramey-Alam Sequential Procedure for Selecting the Multinomial Event which has the Largest Probability

Ramey and Alam 1979 proposed a closed sequential procedure for selecting that one of k >2 multinomial events which has the largest probability. They provided tables of constants necessary to implement their procedure and, based on these constants, they calculated certain performance characteristics of their procedure. In the course of devising a fundamentally different procedure and studying its performance, we had occasion to check their constants and associated performance characteristics. We found quite a few of them to be incorrect. In the present paper we provide extended sets of correct constants and associated performance characteristics (some of which were not provided by Ramey and Alam), and describe the methods that we used to calculate them.
