葡萄酒质量评价的数学模型.rar

摘要:本文先对两组评酒员的评分结果的显著性和可信性进行单因素方差分析，从而得出有效数据。运用这些有效数据，并根据其酿酒葡萄的理化指标和葡萄酒的质量对酿酒葡萄进行分级。接着分析酿酒葡萄与葡萄酒的理化指标之间的联系及酿酒葡萄和葡萄酒的理化指标对葡萄酒质量的影响。最后运用多元线性回归分析，建立运用葡萄酒的理化指标来评价葡萄酒的质量的数学模型。

关键词:单因素方差分析 ；相关分析 ；多元线性回归分析  

Abstract: In this paper, we  will  use the single-factor analysis to assess the significance and  credibility of scores resulting from the two groups of  tasting members to arrive at valid data. Then use  these effective data to classify  wine grapes based on the physical and chemical indicators of the wine grape and wine quality . Followed by analysis of the link between the physical and chemical indicators of the wine grape and wine . Finally, use multiple linear regression analysis to establish the mathematical model which is using wine physicochemical indicators to evaluate the quality of the wine .

Key words: Single-factor analysis of variance ；Correlation Analysis；Multiple linear regression analysis
