Losses follows a lognormal distribution with u=6.9078 sigma=2.6283. A policy covers losses subject to a 1000 franchise deductible and a 100,000 policy limit. Determine the average payment per paid claim. .................................................................... The solution in book is as below. E(X ^ 100,000)-E(X ^ 1000)=9364 Averag per claim=9364/(1-F(1000)) For a franchise deductible, each paid claim get 1000 more. The answer is 19,728. ..................................................................... My problem is why not use E(X ^ 101,000)-E(X ^ 1000) I think there is a 100,000 policy limit,but not a maximum cover loss. If it says there is a maximum cover loss,the solution in book will be right. Can anyone tell me what's wrong with my solution? Thank you very much. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 219.85.171.163
