因子分析中变量和样品空间的统一

以空间结构分析为基础，提出了一个统一的变量和样品空间，由此得到因子空间，依据因子空间中变量和样品的相关性，很容易确定样品点群的成因，还讨论了因子分析中变量坐标和样品坐标的概念，指出因子得分不是样品的坐标，因而把因子得分图看作为因子空间坐标图是不合适的。

COMBINATION OF VARIABLE AND OBJECT SPACES IN FACTOR ANALYSIS

Based on the analysis of spatial structure this paper proposes a combined Variable and object space from which a factor space can be derived.Based on the correlation of variable and objects in the factor space,the genesis of the objects cluster can be easily identified.The auther also discusses the concept of variables coordinate and objects coordinate in factor analysis, and points out that the factor scores are not objects coordinate therefore it is not justified to consider a factor score plot as a coordinate plot of factor space.
