Information content of a random variable Random variable x Outcome of a random experiment Discrete R V takes on values from a finite set of possible outcomes PMF: P(X=y)=Py) How much information is contained in the event X=y? Will the sun rise today Revealing the outcome of this experiment provides no information Will the Celtics win the NBa championship? Since this is unlikely, revealing yes provides more information than revealing Events that are less likely contain more information than likely events

Marciano Siniscalchi October 28, 1999 Introduction [Again, by and large, I will follow OR, Chap. 8, so will keep these notes to a minimum.] Review of key definitions Recall our three payoff aggregation criteria: discounting, i.e

These notes essentially tie up a few loose ends in Lecture 8; in particular, I exhibit examples of inefficiencies in first- and second-price auctions. I would also like to briefly comment on Questions 1 and 2 in Problem Set 2

1、复数的代数式:F=a+jbj=√-1 2、复数的矢量表示 3、复数的三角式:

1.n维向量的概念 定义2所谓数域P上一个n维向量就是由 数域P中n个有次序的数a1,a2,…,an所组 成的数组,这n个数称为该向量的n个分量,第 i个数a称为第i个分量 分量全为实数的向量称为实向量, 分量全为复数的向量称为复向量
