Complete separation example

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

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
