我找到了这个 occupation classification:
http://www.bls.gov/soc/2010/soc152041.htm 里面也有business statistical anlaysis

发帖数: 6435 | 4 这三个哪个比较有用 (转到不做 Bench work 的领域)?
Image anlaysis 应该是 MatLab, bioinformatics 应该是 R
Python 可以干嘛? 转码公?
哪个最容易学? |

发帖数: 266 | 5 我用下面的简单程序得到了 communality 和 covariance matrix S of the same data
。 然后想算 Specific variances. 根据定义应该是 Specific variance=Sii-
communality. 但是不知道为什么有的Sii的值比communality小。这是怎么回事啊？ 高
人指点一下吧。
程序：
proc factor data=test method=principal covariance;
run;
proc corr data=test cov;
var X1-X7;
run;
My summarized output values:
Variable Factor1_loading Communalities Sii Spedific_Variances=Sii-
communality
