  • Abstract
    A Bayes approach is used to test the equality of two reliability functions when the underlying distributions of the times-to-failure are lognormal. Using the method of moments it is found that a normal approximation of the posterior distribution of the threshold parameter is better than an approximation based on the Student t-distribution. Analytic foundations of the conclusions are provided
