查询词典 unbounded interval

First of all, we introduce some interval methods and propose a new approach to find confidence interval for the slope in homoscedastic measurement error models. The performance of the interval estimation is compared in terms of both coverage probability and its diameter via simulation studies. Second, we suggest two approaches to estimate confidence intervals for the slope and joint confidence regions for both intercept and slope in heteroscedastic measurement error models. Application of these methods are illustrated with real data sets.

首先，当测量误差的变异是同质性时，我们对斜率项参数建构信赖区间，除了回顾已发表的方法外，也提出一个新的方法，建议的区间方法分别和已存在的方法做模拟比较，比较的标准建构在覆盖机率和平均长度上；另外，当测量误差的变异是异质性时，我们不仅对斜率项参数建构信赖区间提出新的方法，也对截距项参数和斜率项参数建构联合信赖区间。

一般来说，讨论二次函数在区间上的最值，主要看区间是落在二次函数的哪一个单调区间上，从而用相应的单调性来求最值。

These constructional methods can be used to treat many problems, the numerical results show that the given interval extension has smaller excessive width relative to the range of the functions over a domain.

In the final chapter, we discuss interval polynomial approximation of rational surfaces. Firstly, we briefly state the interval-surface approximation based on the Taylor Expansion, and later, we give out a better interval-surface approximation based on the optimization method, which is also the main work of this paper.

第四章主要介绍了有理曲面的区间多项式的逼近，首先简单介绍了基于泰勒展开来做的区间曲面逼近，后面是本文的主要工作，我们基于优化方法得到了更好的区间曲面逼近，它也是本文的重要部分。

For a given proportion p (where p is the confidence level), a confidence interval for a population parameter is an interval that is calculated from a random sample of an underlying population such that, if the sampling was repeated numerous times and the confidence interval recalculated from each sample according to the same method, a proportion p of the confidence intervals would contain the population parameter in question.

对于一个比例 P而言，一个群体参数的置信区间中的区间是由一个基础群体的随意样本计算出的，假如样本被重复了无数次，置信区间也根据每个样本，以同样的方法重新计算，那么这个置信区间中的比例 P 将要重新定论。

In this thesis, we present a new channel scan method called "random scan" to reduce the delay. The scheme divides the beacon interval into several sections. In each beacon interval, only one section will be scanned and it will take multiple beacon intervals to scan all the section to cover the entire beacon interval.

在本论文我们提出一个减少IEEE 802.11无线网路之漫游所造成服务中断的机制称为随机扫描，此机制将标记间隔切割成数个区段，在每个标记间隔中，只对一个区段进行扫描，剩下的时间可继续正常的传输，以降低服务被中断的时间。

The progress intervals between stages of the disease were estimated using left-censored and interval censored Markov chain models with a 6-year follow-up simulation. Results showed an annual preclinical incidence rate of 5.7 per 1000 for the high-risk group. The mean sojourn time was 1.90 years (95% CI=1.18-4.86). The proportion of interval case increased with the screening interval.
