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。The confidence tests can also bring more convenience in engineering, as that the tests for the percentile and percentage of normal population that are difficult in hypothesis tests can be easily solved by the present method
不但比傳統的正態分佈假設檢驗和抽樣檢驗具有更高的精度,而且更加便於應用,許多假設檢驗和抽樣檢驗難以處理的問題(如母體百分率和百分位值的檢驗) ,採用置信檢驗可以容易地得到解決。In this paper, i study above two issues and gain some results as follows : 1. under population follow normal distribution hypothesis, designing combine median - range adaptive control charts with variable sampling interval, variable sample size and variable control limit. it may be regarded as previously median - range extension
在假設總體服從正態分佈的條件下,設計了抽樣區間,樣本容量和控制限都變化的全變化參數的中位值-極差聯合控制圖。它是以前的中位值-極差聯合動態控制圖的推廣。The normal distribution is suitable to express the daily arrival distribution. and the analytic approach of distribution parameter provides an academic base for the traffic sampling and survey at a waterway lock
( 2 )研究了船閘日到船的分佈規律,指出其近似服從正態分佈,分佈參數的確定方法為船閘交通量的抽樣調查提供了理論基礎。Variable sampling plans for truncated normal populations
