摘要
基于均值填补缺失数据方法,研究Rayleigh分布总体参数的极大似然估计问题及两个Rayleigh分布总体参数相等的假设检验问题,证明了基于均值填补数据的极大似然估计的强相合性以及渐近正态性,给出了检验两总体参数相等的检验统计量以及检验统计量的极限分布.
Based on the method of imputing missing date with mean,the maximum likelihood estimations of Rayleigh distribution and hypothesis test on the equality of two Rayleigh distribution parameters are studied.The strong consistency and asymptotic normality of maximum likelihood estimation are proved. Furthermore,statistic on testing the equality of two Rayleigh distribution parameters and its limit distribution are provided.
