The flatness is one of the form tolerance.It is significant to measure and assess the flatness in measuring of the geometric parameter.Based on the principle of the least square method,the mathematical model of ideal plane is presented for analyzing flatness error.Excel is used to calculate flatn...
最小二乘法Least Square Method,做为分类回归算法的基础,有着悠久的历史(由马里·勒让德于1806年提出)。它通过最小化误差的平方和寻找数据的最佳函数匹配。利用最小二乘法可以简便地求得未知的数据,并使得这些求得的数据与实际数据之间误差的平方和为最小。最小二乘法还可用于曲线拟合。其他一些优化问题也可通过...
The OLS method aims to minimize the sum of square differences between the observed and predicted values, considering potential issues of multicollinearity. That way, the vector β of the coefficients can be estimated by the following formula β = (X’DX)-1 X’ Dy with X the matrix of th...
