A Bayes test of homogeneity of several means for one parameter exponential populations

摘要

The problem of testing the homogeneity of k (k greater than or equal to 2) mean time between failures (MTBF) vs, multiple t-slippage alternatives (1 less than or equal to t < k) has been considered for the one parameter exponential distribution. The exact null distribution of a Bayes test has been derived for selected values of k and t. Several approximations for computing the percentage points of the test statistic are also investigated. Simulated examples are included to illustrate the test. (C) 1999 Published by Elsevier Science Inc. All rights reserved. [References: 11]
