摘要
给出了类相关系数的定义,利用此定义可以在初等函数类中,优选出对拟合曲线相关的函数类,这就避免了选取表达式的盲目性,并结合具体实例计算是很有效的.
The definition of coefficients of class correlation is introduced. By this definition, the function class that related to the fitting curve can be well chosen from the elementary function class, and therefore, the uncertainty can be avoided in chosing representations. This is proved very off effective in practical calculations.
