查询词典 estimate

To choose the reasonable exceedance threshold, mean excess function and De-Haan moment estimate are used.

为了选择合理的超越门限，采用平均剩余函数和De-Haan 矩估计相结合的方法。

We give a simple and practical method to decide on exceedance threshold. Based on the linearity of mean excess function which is a qualitative means,this method uses moment estimate plot to analyze quantitatively the varying trend of shape parameter with changing thresholds.and combines these two means to choose reasonable threshold.

我们给出了确定超越门限的一种简单实用方法，该方法基于平均剩余函数图形的线性性这种定性方法，利用矩估计图定量分析形状参数估计随门限值变化趋势，将两种方法相结合来确定合理的超越门限。

There are totally five chapters in the paper. Chapter 1 is the introduc-tion,and extreme value theory and methods and modelling for returns fat tails are introduced systematically in Chapter 2.This chapter also presents mean excess function and de Haan's moment estimate to decide on the reasonable exceedance threshold. Chapter 3 describes in detail non-linear time series mod-els such as GARCH models and the corresponding statistical inferences,and it also gives modelling and statistical analysis methods for returns series. Chap-ter 4 uses the models in Chapter 2 to analyzes the daily returns for Shanghai complex index and Shenzhen complex index in the Shanghai and Shenzhen stock markets. Chapter 5 applies the models in Chapter 3 to the volatility analysis of the two stock indices returns.

论文总共五章：第一章是引言部分；第二章系统介绍了极值理论方法和收益率厚尾的建模方法，给出了平均剩余函数法和de Haan矩估计相结合的方法确定合理的超越门限；第三章详细论述了非线性时间序列模型GARCH类模型及其统计推断，并且给出了收益率时间序列波动的建模和统计分析方法；第四章利用第二章的模型对国内沪深两市大盘指数上证综指和深证综指日收益率数据分布的厚尾进行了实证分析；第五章将第三章的模型应用到两个股指日收益率时间序列的波动分析。

This paper presents a Bayes method to estimate the expected proportions for high-way contingency tables appropriate when prior knowledge about the interaction effects can be described by a particular kind of exchangeability assumption.

用Logits变换方法来讨论列联表的贝叶期估计，这时的估计称为贝叶斯对数线性估计，最早是由Lconard（1973，1975）提出的。

Among third-generation Hispanic and Asian Americans, exogamy -- marriage outside one's ethnic group or tribe -- is at least 50 percent, he and others estimate.

By introducing the exogenous supply shock variable into Phillips Curve and adding asset prices (e. g. housing price and stock price) and the exogenous demand shock variable to IS Curve, this paper applies GMM method to estimate the extended IS-PC Model between 1996 and 2006. The empirical results show that housing price has a notable positive impact on the output gap, while share price doesn't have. Lastly, the article puts forward corresponding enlightenments.

本文在菲利普斯曲线的解释变量中引入外部供给冲击变童，在IS曲线中引入了房价、股价等资产价格和外部需求冲击变量，以我国1996-2006年的季度数据为样本、采用GMM方法佑计了扩展后的IS-PC模型，实证结果显示房价对产出缺口有显著的正向影响而股价对产出缺口的影响不显著，并在此基础上提出了相应的政策启示。

This gave me a lot of think, royal in those days suffer a defeat and today of 9 cities suffer a defeat, its immanent cause is same: They can gain a success in the moment of truth, not be what concept absolutely is identical, and of the intention in the process that negotiating handle every detail, estimate oneself not exorbitantly absolutely.

这给了我很多思考，盛大当年的失利和今天九城的失利，其内在原因是一样的：他们在关键时刻能取得成功，绝不是什么理念的相同，而在谈判的过程中用心的对待每个细节，绝不过高地估计自己。
