Consider N objects on which two correlated measurements X and Y can be made. Assume that the probability that the Y measurement meets a certain specification is gamma. We present a method whereby a maximal subset of m out of the N objects can be chosen, based on the observed X measurements, so that there is a high probability that a large proportion of the selected subset will meet the desired specification related to the Y measurement. The method we propose uses the conditional probabilities that Y will meet the specification given by the observed value of the xs. The procedure compared favorably with one suggested by Owen, Chen, and Li but has the advantage that no special tables are needed. Author
