桶子们,我这样写有没有出错呢?为什么结果不满足约束条件呢?程序是这样的,
proc nlin;
parms c0=-0.3 c1=0 to 1 by 0.01 c2=0 c3=0 c4=.1 c5=.1 c6=.3 c7=.1 c8=.1;
model r=c0+c1*w1+c2*w2+c3*w3+c4*w4+c5*w5+c6*w6+c7*w7+c8*w8;
bounds 0<=c1<=1, 0<=c2<=1, 0<=c3<=1, 0<=c4<=1, 0<=c5<=1, 0<=c6<=1,
0<=c7<=1,0<=c8<=1;c1+c2+c3+c4+c5+c6+c7+c8=1;
run;
quit;
为什么c1+c2+c3+c4+c5+c6+c7+c8不等于1呢?后面的Bound0,Bound2,Bound4及它们的estimate又是什么东西呢?
