And through simulation study,C_(1,t) (t= 2,3,4) are compared with Pielou s nonrandomness index a and Holgate s H.

本文导出了一组基于两个最近个体距离X_s和X_t的空间格局非随机性检验统计量C_(S,t),并通过模拟研究,将它们与Holgate的指标日以及Pielou的指标口进行比较,最后将其应用于两个天然林分的格局分析。

Based on the iteration algorithm which is proposed to deal with non-random censoring data in past paper,the data-filling method is modified so that the virtual complete data obtained from the algorithm is much closer to the real complete data in the case of Weibull distribution under type I censoring data.

基于作者曾提出的处理非随机删失数据的迭代算法,针对Weibull分布相同定时截尾型试验数据,通过改变数据的填补方式,在保证由算法所得的参数估计的相合性和不变性的前提下,使得改进后的算法所得的虚拟完全数据更接近于真实的完全数据。

Based on the moment invariance criterion and corresponding algorithm which is proposed to deal with non-random censoring data, in this paper, the consistency of estimator is proved in the case of the Weibull distribution under type I censoring data, through controlling the quartile probability of the data filling algorithm.

利用处理非随机删失数据的矩不变准则及相应算法,本文针对Weibuu分布相同定时截尾型试验数据,通过控制算法中填充数据的分位概率,证明了通过迭代算法所得到的参数估计的相合性。
