摘要
数据拟合的方法很多,每种方法各有特点.探讨了积分准则下的数据加权拟合函数的方法,称为加权最小二乘积分法,并给出了三个常用拟合函数具体形式.
The data fitting has a good many methods,each method has itself characteristic. This paper discuss the the method of dada fitting in intergral rule,that is intituled the weighted least squares integral method,and gives three format of fitting function in common use.
