1、书上作业：P317“取β=0.75，t=50,100,150，其他参数同上，计算结果表明，当t增加时和均有所减少”写出程序及结果。模型求解求解的程序如下：n=300;lambda=0.6;p=0.05;bg=0.2;beta=0.75;t=50;nn=50;form=n:n+nnj(m-n+1)=jm(m,n,lambda,p,bg,beta,t);endj'其中函数程序为:functiony=jm(m,n,lambda,p,bg,beta,t)q=1-p;bb=0:m-n-1;pk=pdf('bino',bb,m-t,p);temp=sum((m-n-bb).*pk);y
2、=(q*m-(q-beta)*t-(1+bg)*temp)/(lambda*(n-((1-beta)*t)))-1;求解的程序如下：n=300;nn=50;p=0.1;j=10;form=n:n+nnpp(m-n+1)=pj(m,n,j,p);endpp'其中函数程序为:functiony=pj(m,n,j,p)bb=0:m-n-j-1;t=50;pk=pdf('bino',bb,m-t,p);y=sum(pk);取p=0.05，0.1；t=50,100,150；bg=0.2，0.4；j=5，10，得到计算结果。（对照书本上可将计算结果制定成表格）实验结果：表1p=0,05
