摘要
探讨了最小二乘法的基本原理、几何解释、线性拟合和若干非线性拟合及其在物理、化学等学科中的应用。
In this paper we have tried to probe into some important aspects of the least quare method,involving the fundamental ,geometrical explain and the various kinds of fitting methods such as the linear and nonlinear fittings.We also investigate the application of the least square method in the field of physics, chemistry and so on.
