你给的页面里面提到：
What are the techniques for dealing with complete separation or quasi-
complete separation?
... ...
Exact method is a good strategy when the data set is small and the model is
not very large. Below is a sample code in SAS.
proc logistic data = t2 descending;
model y = x1 x2;
exact x1 / estimate=both;
run;
这表明exact logistic regression可以用来解决data complete separation的问题。
但complete separation并不是degenerate

The Occupy Wall Street movement has gotten a lot of press lately. Basically,
the movement amounts to a mass of people who are pissed off about the
direction the country is taking and have decided to set up shop not only
near Wall Street but all over the nation. And that’s fine, so far as it
goes. I understand and share some of their frustrations. But what I don’t
particularly like is their approach. Who exactly are they trying to
influence? Congress? State governments? Then why are they ... 阅读全帖 |

发帖数: 766 | 3 Snatner Snell 1980 proposed the exact unconditional CI for two independent
proportion difference.
if one group is 0/n... is the CI avaible ?
it is strange for me
as i use proc freq; tables trt*y; exact riskdiff;
(i could not generate exact CI if one group is 0/n )
but if i changed to
proc freq; tables trt * y ; exact or riskdiff; run;
the exact CI for rate difference would be generated in outputs.
is this CI from Santner Snell 1980 ? |

发帖数: 2757 | 4 那个conditional probability是我信口开河
你说的这个exact logistic regression其实是Exact Conditional Logistic
Regression,exact只是实现的方法, conditional才是统计的思想
做conditional 的原理在于认为某些parameter是Nuisance parameter,和自己要
estimate的parameter无关,conditional logistic regression的根本就是condition
out the nuisance parameters |

selling off its massive stockpile of U.S. Treasury debt. Sometimes, their
