由内积的定义():XxX→fa,B∈F,txy,z∈X 1.对第一变元的线性: (ax+By, z)=(, 2)+(y,z) 2.共轭对称性: (x,)=(.x) 3.正定性: xx)≥0且(x)=0x=0 中的条件1和2,可得

Our task How to estimate and test discount factor model. Ep,=E(m (data 1, parameter)) 1. Bring an asset pricing model to data to estimate free parameters. For example, parameter,yinm=B(c+1/c)-y Or the b in m=b f 2. Evaluate the model, is it a good model or not? Is another model better?

3.1.1平行四边形的有向面积和平行六面体的有向体积具有的三条性质 在解析几何中已证明,给定二维向量空间中的单位正交标架,设向量a,B的坐标分别 为(a1,a2)和(b,b2),则由向量a,B张成的平行四边形的有向面积为ab2-a2b,这里记 为;给定三维空间内右手单位正交标架,设向量a,B,y的坐标分别为(a1,a2,a3)

一、多项式的概念 中学多项式的定义:n个单项式(不含加法或减 法运算的整式)的代数和叫多项式。 例:4a+3b,3x2+2x+1,y- 在多项式中,每个单项式叫做多项式的项。这是 形式表达式。 后来又把多项式定义为R上的函数:

Spearman等级相关分析 Analyze\\ Correlate Bivariate 问题:某地做肝癌病因研究,调查了10个乡肝癌死亡率 (1/10万,用Y表示)与某种食物中黄曲霉素相对 含量(用Ⅹ表示)见下表,试作等级相关分析?

Random walks 1 Random walks a drunkard stumbles out of a bar staggers one step to the right, with a canal lies y steps to his right. Thi I equal p second, he either staggers one step to the left or probability. His home lies r steps to his left, and everal natural questions, including 1. What is the probability that the drunkard arrives safely at home instead of falling into the canal? 2. What is the expected duration of his journey however it ends? The drunkard's meandering path is called a random walk. Random walks are an im- portant subject, because they can model such a wide array of phenomena. For example
