基于EM算法学生成绩的因子分析

Factor analysis of students' scores based on EM algorithm

用EM算法对学生成绩进行了因子分析,通过MATLAB软件的编程计算发现,找到的潜在变量与传 统的课程分类基本一致.

The data of students' scores are analyzed by the factor analysis based on EM algorithm. Using the procure compiled of MATLAB software,we find that the latent variables are the same as those of traditional classifying of subjects.
