【摘要】 本文在运用无偏转换思想找到区间数据均值估计的基础上,对所找到的估计量的方差进行了研究.针对区间截断情况1和区间截断情况2,找到了估计量方差有限的条件.当截断随机变量的分布在某种程度上比被截断随机变量的分布尾部更厚时,方差有限的估计量可以取到.更多还原

【Abstract】 The estimator of expectation of interval censored data can be established by means of unbiased transformations.In this paper,we go further to study the variances of these estimators.In interval-censored Case 1 and interval-censored Case 2,when the tail of the density function of the censoring variable is thicker than that of the density function of the censored variable to some extent,the estimators with finite variance can be easily obtained.更多还原
