摘要
已知酿酒葡萄的好坏与所酿葡萄酒的质量有直接的关系,葡萄酒和酿酒葡萄监测的理化指标会在一定程度上反映葡萄酒和酿酒葡萄的质量等条件,建立模型解决问题。文章主要通过正态分布、方差检验,建立主成分分析、多元线性回归、聚类分析、相关系数和逐步回归模型来解决问题。
It is known that the quality of wine grapes has a direct relationship with the quality of the wines being brewed.The physical and chemical indicators of wine and wine grape monitoring will reflect the conditions of wine and wine grapes to some extent,and establish models to solve problems.This paper mainly solves the problem by using normal distribution and variance test,establishing principal component analysis,multiple linear regression,cluster analysis,correlation coefficient and stepwise regression model.
