一、最小二乘法(Least Square Method) 1.1 线性回归概念【转自百度百科】 线性回归是利用数理统计中回归分析,来确定两种或两种以上变量间相互依赖的定量关系的一种统计分析方法,运用十分广泛。其表达形式为y=wx+εy=wx+ε,εε为误差服从均值为0的正态分布。 在统计学中,线性回归(Linear Regressi...
最小二乘法 least square method 最小二乘法(又称最小平方法)是一种数学优化技术。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最小化能量或最大化...
