On Multiple Comparison of Geometric Means of Exponential Parameters via Graphical Model

摘要: This paper develops a multiple comparison method for finding an optimal ordering of K geometric means exponential parameters. is based on the paired experimental arrangement whose results can naturally be represented by completely oriented graph. Introducing posterior preference probabilities and stochastic transitivity conditions to graph, we obtain new graphical model that yields criteria in comparison. Necessary theories involved some computational aspects are provided. Some numerical examples given illustrate efficiency suggested method.
