CFA 的内容我不熟悉，见谅。
有个外部命令可以参考：
findit confa

confa from http://fmwww.bc.edu/RePEc/bocode/c
    'CONFA': module to perform confirmatory factor analysis modeling / confa
    fits confirmatory factor analysis models by maximum / likelihood.  / KW:
    confirmatory factor analysis / KW: maximum likelihood / Requires: Stata
    version 11 / Distribution-Date: 20100216 / Author: Stanislav Kolenikov,

谢谢，我仔细研究以下这个命令。
