发帖数: 84 | 1 case study: credit card insurance profit per customer
cost of mailing $0.5, response rate 1%, average balance per month $1000,
insurance charges 1% of average balance monthly, customer claim rate 5%
(once insured customer files a claim, the balance will be wiped and C1
lose $1000).
Question: profit per customer, graph claim rate vs response rate, graph
profit vs response rate and find the response rate for maximum profit (r=1%)
N=total number of mails sent
profit= N*1%*1000*1%-N*0.5-N*1%*5%*1000=-45N , right?
profit vs response rate
y=x*1000*1%-0.5-x*5%*1000 怎么看都是个负的profit啊。。。 | h**a

发帖数: 1427 | 3 N*1%*1000*1%-N*0.5-N*1%*5%*1000怎么就出来-45N了。。

发帖数: 323 | 4 customer claim rate 5% 是monthly还是annually的？
如果是annually应该是
profit= N*1%*1000*1%*12-N*0.5-N*1%*5%*1000=0.2N | x*****y
