本文给出了全样本场合下卡帕分布参数的矩估计,证明了矩估计的唯一存在性,并通过Monte—Carlo模拟考察了估计的精度;最后通过北京、天津、南京、上海、广州降水量的实际数据说明本文方法的可行性。
In this paper, the moment estimators of Kappa distribution are derived under full sample size case, and the uniqueness and existence of estimators are proved. Then, the precisions of q~he estimators are investigated by Monte-Carlo simulations. Finally, the feasibility of this method is illustrated by the actual precipitation data of Beijing, Tanjin, Nanjing, Shanghai and Guangzhou.
