An Improved Approximate Two-Sample Poisson Test
提出一种改进的近似检验方法，用于比较两个泊松过程的失效率是否相等，通过数值结果证明其在显著性水平和检验功效上优于传统方法。
SUMMARY An improved approximate test for the equality of the failure rates of two Poisson processes is proposed. The significance level, power and experiment length needed to achieve a specified power are compared to a previously studied approximate test. Both equal and unequal time intervals are considered. Numerical results show that this test, based on the variance stabilizing transformation, is superior in achieving nominal significance levels and powers over a wide range of parameter values and experiment lengths.
