Principal Component Analysis is very similar to Factor Analysis, and the two procedures are sometimes confused. Both procedures are built on the same mathematical techniques. Factor Analysis assumes that the relationship (correlation) between variables is due to a set of underlying factors (latent vari...

首先我们随机产生50个100维且N\sim(u,I)的数据,这里可以看到样本的数量小于样本的维度,我们要做的是用factor analysis的EM算法把这堆数据的高斯模型给估计出来,我们开始先做数据预处理X-u,以及对参数\Psi和\Lambda初始化,对应如下: clc;clearall;closeall;N=50;%样本数量D=100;%x的维度K=10;%z的维度u=5;...

Factor analysis uses thecorrelationstructure amongst observed variables to model a smaller number of unobserved, latent variables known as factors. Researchers use this statistical method when subject-area knowledge suggests that latent factors cause observable variables to covary. Use factor analysis to id...
因子分析模型, Factor Analysis models 注意, 这里的因子分析, 不是多元分析中的因子分析(与主成分分析类似), 这个因子分析主要出现在遗传评估领域, 比如植物, 林木中多地点数据的分析, 动植物中多性状分析计算遗传相关时. 优势 由于它可以减少方差组分估算的个数, 特别是在多性状时具有优势, 因此在多性状分析时,...
