Complete separation example
Thanks Jarrod, but I'm specifically looking for something where a mixed model is appropriate. My googling has shown me that it happens often enough, but I haven't found much with available data.

Hi Vince, Sex effect on horn type in Soay sheep is completely separated (the trait is partly sex-limited): data(SShorns) m1<-glm(I(horn=="polled")~sex, data=SShorns, family=binomial) Cheers, Jarrod Quoting Vincent Dorie <vjd4 at nyu.edu> on Tue, 4 Mar 2014 12:20:41 -0500:
Hi list, can anyone point me to a data set that exhibits complete or quasi-complete separation when fit as a glmm? It's for a vignette, so something public would be ideal. With thanks, Vince
