Example 5
Using the payoff table in Example 1, determine which project would be chosen using the following decision rules:
(a) maximax;
(b) maximin;
(c) minimax regret.
State of market Diminishing Static Expanding
Probability 0.4 0.3 0.3
Project 1 (100-180) = -80 (200- 500) =-300 (1,000 -1,000) =0
Project 2 (0 -180) = -180 (500-500) = 0 (600 -1,000) = -400
Project 3 (180-180) = 0 (190 -500) = -310 (200 -1,000) =-800
Solution
(a) Project 1 has the highest return in an expanding market.
(b) Project 3 has the highest return in a diminishing market.
(c) Opportunity loss table

【提问内容】example 5里面减去的数据从哪儿来的?Example 1 里面没有啊
【回复内容】您的问题答复如下:
您看一下第一个课件的00:12:04开始,说的是第一道题,里面应该是有这个例子里面需要数据。
您看的还是上半年的课件么?网校已经更新了新的课件,建议您看下半年的课件,因为F5的考试题型已经更新了,所以之间讲课的内容有的不适用于现在的考试了,而且这道例题在新的教材中应该也已经删掉了或者改编了。
祝您学习愉快!祝您顺利通过考试!感谢您对网校的支持!
