摘要
利用判别分析与回归分析的关系，将回归分析中影响分析的方法应用到判别分析中，讨论了一组试验数据对样本线性判别函数精度的影响问题。给出了样本线性判别函数精度的强影响点的定义，以及相应的确定强影响点的统计量及其分布。
This paper uses the relationship of regression analysis and discriminant analysis to apply the method of influence analysis of regression analysis in discriminant analysis to discuss the influence of a set data to the precision of a sample linear discriminant function. The strong influence case is defined and the adaptable statistics and its distribution are presented for the method of determining the strong influence case.
