| 摘 要： | 引入矩阵的对角均差概念，将计算双因素积指标的因素影响值转化为计算矩阵的对角均差。通过适当的变换，商指标、积和指标以及加权平均指标的因素影响值也都能用矩阵方法求解，从而使统计指标的因素分析方法在一定程度上得到了统一与简化。

| Abstract: | The concept of diagonal average difference of matrix is proposed. Based on this concept, calculating the values influenced by factors in double factor product index is transformed into calculating the diagonal average difference of matrix. Through proper transformation, the values influenced by factors in quotient index, product sum index and weighted mean index can also be determined by means of the matrix method, and the factor analysis method of statistical index is thus unified and simplified to a certain extent. |
