零偏变换与经验特征函数相结合的正态性检验

On combining the zero bias transform and the empirical characteristic function to test normality

Bruno Ebner

摘要:

我们提出了一个新的强大的家庭测试的一元正态性。这些测试是基于一个初值问题,在空间中的特征函数源于不动点性质的正态分布的零偏置变换。检验统计量的极限分布在原假设下以及在连续和固定替代项下提供。利用零分布的极限高斯过程的协方差结构,我们推导出了极限随机元的前四个累积量的显式公式,并通过拟合Pearson系统的分布来应用结果。一个比较蒙特卡罗功率研究表明,新的测试是严重的竞争对手,以最强的完善的测试。

英文摘要:

We propose a new powerful family of tests of univariate normality. These tests are based on an initial value problem in the space of characteristic functions originating from the fixed point property of the normal distribution in the zero bias transform. Limit distributions of the test statistics are provided under the null hypothesis, as well as under contiguous and fixed alternatives. Using the covariance structure of the limiting Gaussian process from the null distribution, we derive explicit formulas for the first four cumulants of the limiting random element and apply the results by fitting a distribution from the Pearson system. A comparative Monte Carlo power study shows that the new tests are serious competitors to the strongest well established tests.
