y********9 发帖数: 13 | 1 急问高手,怎样在SAS实现logistic regression里independent variable重要性排序?
(所有的independent variable都significant,P-value all <0.0001.但想知道哪个
variable最重要,哪个最不重要,需要按importance ranking score排序)。多谢!!

i would guess you have a very large sample.
Reducing sample could reduce the significance level. I know this is a bad
idea, but at least you can try it. |

correponds to the least significant predictor. |
