澳洲代寫案例 一. The implications
1. The statistics and frequency of good_bad are shown in table 1 and table 2.
Table 1  Statistics of good_bad

N Valid 1000
Missing 0
Mean .30
Std. Deviation .458
 
,Table 2  Frequency of good_bad
  Frequency Percent Valid Percent Cumulative Percent
Valid 0 700 70.0 70.0 70.0
1 300 30.0 30.0 100.0
Total 1000 100.0 100.0  
 
From table 1 and table 2, we can know the mean and the Std. Deviation of good_bad is 0.3 and 0.458. The probability is 70% that the customer is a good customer, and it is 30% that the customer is a bad one.
澳洲代寫案例 2. According to the above analysis, a customer is a good one or bad one, the probability is 70% or 30%. And the cost to the bank of granting a loan to a bad customer is five times higher compared to the profit from granting a loan to a good customer. Suppose the profit from granting a loan to a good customer is A, and the total funds is limited. Then, if a good customer as a bad one, the profit of the bank will get is m1=-a+(0.7*a-0.3*5*a)=-1.8*a, and if a bad customer as a good one, the profit of the bank will get is m2=-5*a-(0.7*a-0.3*5*a)=-4.2*a. For any one customer, if he is classified as a good client, the profit of the bank will get is m3=0.7*a-0.3*5*a=-0.8*a, else, the profit of the bank will get is 0. The cost of a bad customer as a good one is 2.33 times than the cost of a good customer as a bad one. Thus, in the process customer classification, we should tend to classify the customer as a bad client
