最小二乘是由方程式近似的数据点的一组的方式,让你预测中间值,或计算的数据的一些措施。您可能已经通过绘制通过数目的数据点图上绘制的直线近似的趋势线。最小二乘这不只是“装修”,但在数学的方式,最大限度地减少错误,从而导致。我的单元延伸最小二乘从仅仅是一种直线拟合到高阶多项式为更复杂的数据(其中可能有一平方律拟合的物理原因,例如),或更好的匹配的数据。-Least-squares is a way of approximating a set of data points by an equation

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熵用最小二乘法来表达。-Least squares method (also known as the least squares method) is a mathematical optimization techniques. It
