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 as are 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
同時,由於poisson分佈的特性,我們知道不存在其參數區間長度小於0 . 5的置信區間,基於這些情況,我們主要展開了以下兩個方面的研究:一是利用數值計算分析與理論分析的方法對現有的若干置信區間如「精確」置信區間, wald置信區間, bayes置信區間等進行分析比較,發現了一些缺陷,針對這些缺陷,我們進行適當的修正,並得到幾種性質較好的置信區間如:修正大樣本區間jeffreys原則下置信區間二是針對已給定的置信系數與區間長度,我們提出了一種漸近的兩階段區間估計程序,並利用數值計算的方法,在各種置信系數與區間長度限定下,算出了最優的第一階段觀測次數(抽樣量) ,大量數據表明,本文考慮的方法性態良好,具有應用價值。Based on the review of and comment on the concepts and theories of attitude and travel attitude and the current research situations about travel attitude, according to three element theories of the attitude, by way of random sampling of strata, the paper has carried on measurement of travel attitude of zhengzhou city, wuzhi county and yuanyang county resident. in writing this paper, the author designed a travel attitude inventory, which had been proved to be of good reliability and validity. then it carries on factor analysis and cluster ' s analysis to the measurement
