Meanwhile, it could be seen that there does not exist a confidence interval with width less than 0.5 because of the property of Poisson distribution. Based on these conditions, the author mainly carried out research into two aspects of this problem as follows. Firstly, by numerical and theoretical analysis, the author compares some existent confidence intervals, for example,"exact" confidence interval, Wald confidence interval and Bayesian confidence interval, and finds some deficiencies points of the confidence intervals, whose modification version has been proposed .Also, several better confidence intervals such asare also presented .Secondly, for given confidence coefficient and interval width, the author constructs a class of asymptotical two-stage interval estimate procedures. At the same time, under varies restriction of confidence coefflcientent interval width, the optional sample size of the first stage has been computed by numerical computation. The numerical computation shows that the method considered in this dissertation have good properties and applied value.
同时,由于Poisson分布的特性,我们知道不存在其参数区间长度小于0.5的置信区间,基于这些情况,我们主要展开了以下两个方面的研究:一是利用数值计算分析与理论分析的方法对现有的若干置信区间如"精确"置信区间,Wald置信区间,Bayes置信区间等进行分析比较,发现了一些缺陷,针对这些缺陷,我们进行适当的修正,并得到几种性质较好的置信区间如:修正大样本区间Jeffreys原则下置信区间二是针对已给定的置信系数与区间长度,我们提出了一种渐近的两阶段区间估计程序,并利用数值计算的方法,在各种置信系数与区间长度限定下,算出了最优的第一阶段观测次数,大量数据表明,本文考虑的方法性态良好,具有应用价值。

In particular, for recurrent event data, we proposed a novel nonparametric estimator of the survival function and obtained an efficient estimator of the expected total number of events for counting processes. Also we established asymptotic properties of these estimators and investigated nonparametric estimation of survival functions, density functions and hazard functions under various types of incomplete data.
在重复事件发生的情况下,创新地提出了一种生存函数的非参数估计,获得了计数过程中预期事件总数的估计以及这些估计的大样本性质,并在其他各种不完全数据下对生存函数,概率密度和失效率函数等非参数估计进行了深刻研究。

In this paper,with respect to the ordinal variables,the definitions of attribute reduction of dominance-based rough set approach in ordered information systems and ordered decision tables are given.Then the approach of sorting objects comprehensively using rough set theory is brought in to obtain a series of ranks.Based on these ranks,nonparametric methods to analyze correlation between two attribute subsets are introduced,and Spearman rank correlation coefficient is used as a measure of attribute correlation.Based on this measure,a new method of attribute reduction of ordered information systems and ordered decision tables is presented without changing the ordinal information of the universe.
针对有序尺度变量,给出了有序信息系统与有序决策表在优势关系下的粗糙集约简定义;利用粗糙集方法将对象综合排序,进而得到一组秩;根据这些秩,运用非参数统计的思想研究了两个属性子集之间的相关性,并将Spearman秩相关系数作为属性相关性度量;在不改变总体序信息情况下,给出了基于此度量对有序信息系统与有序决策表进行约简的新方法。

We followed tracks and signs of a large group of lion cubs that moved considerable distances, without the guidance or protection of adults. There were approximately ten cubs, and from the size of their spoor, they were no older than a year. These were unusual observations. Generally, lionesses give birth to small litters of 2 – 3 cubs, although they do occasionally synchronise their oestrus cycles and produce litters about the same time. However lion cubs, of that age, are mostly in the company of adults. Textbooks and the scientific literature suggest that one-year-old lions are dependent on the adult lionesses of their pride, and could not survive on their own.
我们跟踪由一大群幼狮留下足迹的其他记号,这些狮子没有其他成年狮子陪同和保护,粗略估计,这群狮子的数量接近10只,他们足迹的尺寸显示他们不会超过1岁,这是不常见的,通常情况下,母狮会生下至少2~3头幼崽,但也有个别例外的时候,然而在这个年龄段的幼狮大都有"母亲"陪同,许多书上介绍,1岁大的小狮在离开狮群母狮的照顾后是无法生存的。
