作出Y与X1,X2,X3之间关系的方程式,不知道该用线性还是非线性回归,急用,
第一次使用百度知道，毕业论文急着用这个成果，身边也没有会用这个的朋友，希望热心朋友可以帮一下忙，

先画一下散点图 看看 是否有线性关系
如果有线性关系 则用线性回归
如果呈非线性关系,采用曲线回归中 多种回归方程后 选择拟合最优的一个

多元非线性回归 用spss做 用SPSS如何做多元回归分析? spss 多元非线性回归如图,怎么在spss中将数据入上述数学模型后,再做非线性回归,求出系数呢?模型是怎么输入的?困扰中 - - 我用spss做的多元线性回归分析, spss 多元线性回归和多元逐步回归一样么?如题.如果不一样,分别这么用SPSS做呢?
