具有未知截断参数的几何分布中参数的UMVU估计

THE UNIFORMLY MINIMUM VARIANCE UNBIASED ESTIMATOR OF PARAMETERS IN GEOMETRIC DISTRIBUTION WITH UNKNOWN TRUNCATION PARAMETER

在具有未知截断参数的几何分布中，分别给出了均值Ｅ（Ｘ），方差Ｖｖａｒ（Ｘ）和ｒ阶阶乘中心矩μ（ｒ）的一致最小方差无偏估计．

The uniformly minimum variance unbiased estimators of three parameters mean E(X), variance Vvar(X) and central factorial moment of order r, μ(r) in geometric distribution with unknown truncation parameter are obtained.
