2.1随机过程的基本概念和例子 定义2.1.1:设(,F,P)为概率空间,T是某参数集,若对每一个t∈T,(tw 是该概率空间上的随机变量,则称X(t,w)为随机过程(Stochastic Process 随机过程就是定义在同一概率空间上的一族随机变量。随机过程X(tw)可 以看成定义在TxQ上的二元函数,固定wo∈Ω,即对于一个特定的随机试验, 称X(t,wo)为样本路径(Sample Path),或实现(realization),这是通常所观测到的 过程;另一方面,固定t∈T,X(to,w)是一个随机变量,按某个概率分布随机 取值

Ch. 3 Estimation 1 The Nature of statistical Inference It is argued that it is important to develop a mathematical model purporting to provide a generalized description of the data generating process. A prob bility model in the form of the parametric family of the density functions p=f(:0),0E e and its various ramifications formulated in last chapter

Ch. 19 Models of Nonstationary Time Series In time series analysis we do not confine ourselves to the analysis of stationary time series. In fact, most of the time series we encounter are nonstationary. How to deal with the nonstationary data and use what we have learned from stationary model are the main subjects of this chapter 1 Integrated Process

Ch. 18 Vector Time series 1 Introduction In dealing with economic variables often the value of one variables is not only related to its predecessors in time but, in addition, it depends on past values of other variables. This naturally extends the concept of univariate stochastic process to vector time series analysis. This chapter describes the dynamic in

Ch. 16 Stochastic Model Building Unlike linear regression model which usually has an economic theoretic model built somewhere in economic literature, the time series analysis of a stochastic process needs the ability to relating a stationary ARMA model to real data. It is usually best achieved by a three-stage
