理解了least-squares solution之后,我们可以回到之前的问题。显然向量 b=(6,0,0) 在矩阵 A 的列空间之外,列空间可以看成是由矩阵 A 的两个列向量 v1=(0,1,2),v2=(1,1,1) 构成的平面,而我们要找的就是 b 到这个平面的最小距离。运用上面的公式 ATAx^=ATb 我们可以得到 x^=(−3,5) ,即 b ...
Deming presents a completely general method for fitting experimental results by least squares and, when this general method is applied to the specific problem studied by Wayman, the same result is obtained. The statement that the solution only passes through the centre of gravity if this is found...
A general least squares solution for successive intervals is presented, along with iterative procedures for obtaining stimulus scale values, discriminal dispersions, and category boundaries. Because provisions for weighting were incorporated into the derivation, the solution may be applied without loss of ...

x <- sol$solution 然而,求解器提出的解决方案是: x = c(0, -0.00998378737371228, -0.201346544072718, -0.100606322374837, -0.00231687038045124, -0.0127853533889169, -0.0503335436656537, -0.0960035800434156, -0.0621270554666326, -0.00514278524360472, -0.92007113767952, -0.00195508366468776, -0.000990748025440275, ...
The least squares solution x^ makes E=‖Ax−b‖2 as small as possible. By calculus: The partial derivatives of ‖Ax−b‖2 are zero when A⊤Ax^=A⊤b. The Big Picture for Least Squares There are no solutions to Ax=b . Instead of splitting up x we are splitting up b=p+e ...
