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.

I will introduce a method to solve this problem when data come from some common life distribution, such as Weibull distribution and Lognormal distribution. In chapter 1, we introduce background of grouped data and how to analyze them with classical methods. In chapter 2, we introduce EM algorithm and show that the estimation of the parameters get through this algorithm is convergent under certain conditions. In chapter 3, we use EM algorithm to estimate parameters in Weibull distribution and Lognormal distribution by grouped data and the simulation shows this method is available.

The paper use the GIS methods to creating the basic spatial information database, and processing the polygon data by overlapping analyst, the linear data by network analysis, the statistic data by join analysis, the evaluate data by superaddition analysis, and these methods make the data collection, organization and analyst more easier, and the thematic map make the result more intuitionistic. Especially, through combined the graphics processing and the spatial data operation organically, the spatial overlapping analyst resolved the division from natural elements to administrative evaluate units.

RMB financial products in this article yield factors for the study of commercial banks in the theory of personal finance and domestic financial product research RMB combing literature based on theoretical analysis from a financial product RMB yield factors, as well as factors product yield on the financial mechanism of the impact and application of new Industrial and Commercial Bank of China fixed-term renminbi financial products based on relevant data, in order to build a yield to maturity, duration, interest rate and money supply measures for the analysis of model variables the above theory can be tested, statistical analysis showed that: RMB Commercial Bank financial products yield to maturity and interest rates, money supply was a negative correlation between the volume, but no significant period of relevance.

本文以人民币理财产品收益率影响因素为研究对象，在对商业银行个人理财相关理论和国内人民币理财产品及其收益率研究文献进行梳理的基础上，尝试从理论层面分析人民币理财产品收益率的影响因素，以及各因素对理财产品收益率产生影响的作用机理，并以中国工商银行已到期2006年、2007年和2008年人民币理财产品的相关数据为依据，构建以到期收益率、期限、利率及货币供给量为变量的计量分析模型，用描述统计方法和斯皮尔曼相关分析对上述理论进行检验，统计分析结果显示：商业银行人民币理财产品的到期收益率和利率、货币供给量呈负相关关系，而与期限没有显著的相关性。
