摘要
多元正态分布是多元统计分析中的一个重要分布,其内容主要包括概念、性质、参数估计与假设检验等,其中概念是基础和前提,因此准确领会多元正态分布概念的思维逻辑非常有必要,该思维逻辑就是推广思想的运用。根据教学体会,阐述了多元正态分布密度函数的导出、合理性、参数含义及推广。
The multivariate normal distribution is an important distribution of multivariate statistical analysis that mainly includes concepts,nature,parameter estimation and hypothesis testing where the concept is the basis and premise,so it is very necessary to accurate grasp the logical thinking of the multivariate normal distribution concepts. And logical thinking is to promote the use of ideas. According to the experience of teaching,I elaborated export,rationality,definition and promotion of multivariate normal density function.
