Summary: The problem of selecting the population with the largest probability of success from among \(k(\geq 2)\) independent Bernoulli populations is investigated. The population to be selected must be as good as or better than a control. It is assumed that past observations are available when the current selection is made. Therefore, the empirical Bayes approach is employed. Combining useful information from the past data, an empirical Bayes two-stage selection procedure is developed. It is proved that the proposed empirical Bayes two-stage selection procedure is asymptotically optimal, having a rate of convergence of order \(O(\exp(-cn))\), for some positive constant \(c\), where \(n\) is the number of past observations at hand.
