求数学函数大神,拜谢 5
x=(7410,6357,6165,6326,6864,5263,5250,7486,40247,30774,28236,18255,13272)y=(203,103,8...
x=(7410,6357,6165,6326,6864,5263,5250,7486,40247,30774,28236,18255,13272)
y=(203,103,82,111,195,126,134,14,4095,2215,1566,874,336)
z=y/x=(2.74%,1.62%,1.33%,1.75%,2.84%,2.39%,2.55%,0.19%,10.18%,7.20%,5.55%,4.79%,2.53%)
因变量B=(159,123,111,128,162,149154,194,309,259,227,211,153)
求因变量B关于 (x,y,z)的函数,就得到一个公式。 我是数学白痴,希望大神儿施以援手,拜谢! 展开
