本程序主要用于寻找多自变量与单因变量之间的线性拟合以寻找数据之间存在的某种线性关系，并可以实现后期寻找各因素影响主次关系。(This procedure is mainly used to find the linear fit between multiple autonomous variables and single dependent variables to find a linear relationship between the data, and can achieve the latter part of the factors to find the primary and secondary relations.)
