Abstract :Analysis of Reciprocals F-test developed by Miura [1] is used to test the equality of Inverse Gaussian insert ignore into journalissuearticles values(IG); means based on the assumption of homogeneity of scale parameters. However this method is not valid when this assumption is not satisfied. There are some method developed for comparing the equality of the IG means under heteroscedasticity of scale parameters. In this study, we compare the performance of the five commonly used tests in the literature via Monte Carlo simulation study. The tests considered are analysis of reciprocals insert ignore into journalissuearticles values(ANORE); F-test, Parametric Bootstrap Approach insert ignore into journalissuearticles values(PBA);, Generalized p-Value Approach proposed by Tian insert ignore into journalissuearticles values(GPT);, Generalized p-Value Approach proposed by Shi and Lv insert ignore into journalissuearticles values(GPS); and Computational Approach Test insert ignore into journalissuearticles values(CAT);, The goal of this study is to compare these methods under different combinations of parameters and various sample sizes.
