double[,] x =
{ {0.0961,0.1111,0.0934,0.2979},
{0.0974,0.1083,0.1057,0.3125},
{0.1168,0.1265,0.1117,0.3125},
{0.0854,0.1006,0.0893,0.2884},
{0.1012,0.1182,0.1134,0.3296},
{0.0925,0.1035,0.0890,0.3355},
{0.1095,0.1194,0.1119,0.3143},
{0.0952,0.1065,0.0968,0.3169},
{0.0873,0.0983,0.0771,0.3193} };

double[] y =
{ 1031.6,
2632.3,
1373,
1850.8,
2242.2,
3066.9,
2216.7,
1744.3,
2676.7 };

如何编程实现多元线性回归计算得到：
y=ax1+bx2+cx3+dx4+e"
其中abcde是确定的常数？

这么久没人能解，太弱了。
