本文提出了一种用于测试 k 个独立逆高斯总体尺度参数同质性的新程序。基于广义似然比法的思想，推导了一个新的广义p值。给出了一些仿真结果来比较所提出的方法和现有方法的性能。数值结果表明，所提出的测试具有良好的尺寸和功耗性能。
This article presents a new procedure for testing homogeneity of scale parameters from k independent inverse Gaussian populations. Based on the idea of generalized likelihood ratio method, a new generalized p-value is derived. Some simulation results are presented to compare the performance of the proposed method and existing methods. Numerical results show that the proposed test has good size and power performance.
