第10题

Last December 22 a pickup truck slid on an icy bridge over the Elizabeth River near P

ortsmouth,and slammed into the guardrail,where workers were removing scaffolding from a paving project.The impact threw Cornell Taylor,43,more than 70 feet into the frigid water below.Nearby,Joseph G.Brisson,36,was in the wheelhouse of his tugboat.He and his crew were talking about the upcoming holidays when suddenly their chatter was interrupted by an urgent voice:"Man down!"Brisson saw Taylor hit the water."He went down a few times and all I saw was a hand."Realizing there was no time to wait for rescue crews,Brisson took off his shoes and handed his wallet to a co-worker,then jumped feet-first into the 40-degree water.Swimming to Taylor,Brisson helped the disoriented man get his face above water."I told him I was not going to let him go,that if he went,I was going with him."The river current was freezing."I couldn't feel my legs,arms or hands,"Brisson said.He locked his legs around Taylor's waist and kept the injured man float and talking."I told him we were going to be all right,that we were both going to enjoy Christmas."Finally, after about 30 minutes in the water,the men were pulled to safety.Calling himself "a normal Joe,"Brisson says,"I have a family.I thought about that.But I thought about how life is very important,I couldn't let anything happen to him."

第11题

利用CHARITY.RAW中的数据回答本题。变量respond是一个虚拟变量，如果一个人对慈善组织最近的邮

件做出捐助响应，这个变量就等于1.变量resp last也是一个虚拟变量，如果一个人对慈善组织前面的邮件做出捐助响应，这个变量就等于1。avggift表示过去的平均捐助额(以荷兰盾为单位) ， propres p表示此人对过去慈善组织寄来的邮件做出捐助响应的次数比例。

(i) 估计一个将respond与resplast和avggift联系起来的线性概率模型。以通常的形式报告结果，并解释变量resplast的系数。

(ii)过去捐助的平均水平看来会影响做出捐助响应的概率吗？

(iii) 在模型中增加变量propres p并解释其系数。(这里须注意， propresp增加1是最大可能变化。)
