基于灰色多元线性回归的河南省粮食产量预测

摘要

Based on analyzing 8 factors influencing the grain yield in Henan Province from 1990 to 2009, the paper found out the main factors. The paper built multivarite statistics analytical model and forecasted the grain yield of Henan in the next 5 years by muitivarite statistical analysis and Eviews software.%对河南省1990-2009年影响粮食总产量的8个因素进行灰关联分析,找出影响河南省粮食产量的主要因素.运用Eviews软件,对主要影响因素建立多元线性回归模型并预测未来5 a河南省粮食总产量.
