这是一张Excel表单，总共有几千行数据，我选取了一些具有代表性的行，粘贴出来，大家可以看到有A,B,C,D,E 5个字段，至于Ratio这个字段做什么用的，我问了老板，他的回答是：不知道。。。需求就是，假设有个字段P,如何根据每行的A[n],B[n],C[n],D[n],E[n]得到P[n],即是找出P = F(A,B,C,D,E),的这个F()然后得到P。坦白地说我真的是懵了。在我看来，更离谱的是，假如又有字段F,G等加入进来，这个F()要具有扩展性，即P = F(A,B,C,D,E,F,G), F依然适合。
我所知道的需求就这么多，问了一些，老板说他自己也不知道。
所以我想请教的是：1，这个是可以做的么；2，假如n-dimension的不可以做，那么现有的这个5-dimision，即P = F(A,B,C,D,E),这是可以做的么（我觉得这一部肯定是可以做的），如果能做，不知道是否能提供一些思路，相关书籍，给与指导； 3，如果不能做，那么我想知道为什么不能做。
十分感激各位的相助。小弟联系方式: mail,lixin19821010@163.com, MSN, lixin19821010@hotmail.com, QQ: 147370451
