摘要
研究了在部分数据缺失且存在测量误差情况下,负二项分布总体参数估计问题以及两总体参数相等的假设检验问题,证明了参数矩估计量的强相合性以及渐近正态性;给出检验两总体参数相等的检验统计量,并考虑了检验统计量的极限性质;并对估计结果进行了随机模拟,进而说明估计的可行性.
It was studied that parameter estimation and the hypothesis testing of two Pascal distribution population with measurement error and missing data and the confidence interval of the difference of the two population parameters was established.Moment estimation of the model parameters was given,which proved the estimators of the strong consistency and asymptotic normality and limiting distribution of the test statistics.Random simulations of the estimation results were also presented to illustrate the feasibility of the estimation.
