The nonlinearleastsquaremethod and functional condition extremum model are introduced to describe the problems and numerical solution of them is proposed.
With the theoretical and practical data analysis, it compares the nonlinearleastsquaremethod (NLS) with the logarithmic linearization least square method (LLLS).
通过理论和实例分析,将非线性最小二乘(NLS)法与常用的对数线性化最小二乘(LLLS)法进行比较。

Trial-and-error method of the linear regression is introduced to determine the reasonable range of geological parameters. And the nonlinearleastsquaremethod to calculate OGIP.
