寻求帮助和合作论文

xiaoshangbin

我现在有一个问题寻求帮助和合作论文。
是这样的，我想要分析的是y 和x $ J8 Y8 m) m( W, D( [( S的关系（见附件），但是x和y好像是没有关系；然而，x和sum-y（就是y的累加）相关性却相当高(0.999)，根据由Excel得到的回归方程，回 * C: y- O R( q; ~) `- b归的sum-y与实测的sum-y误差也很小，但是回归的y 5 t$ J3 [$ a7 ]" `9 t) E值（由回归的第n个sum-y减去实测的第n-1个sum-y得到）与原值就误差很大。我想请教一下，为什么会出现这个问题？能否通过数学方法来解决这个 . |2 M3 Z% j9 i+ E; s9 U- ~问题（就是使回归的y值与原值误差尽量小）？ 此问题如果能够较好解决，可以合作发表数篇SCI文章。
