new TR about when MLE exist in GLM and what to do if not
This is just to alert the list about a new technical report
http://www.stat.umn.edu/geyer/gdor/
that shows how to determine, using exact infinite-precision rational arithmetic
when the MLE exists in a GLM (or for that matter in any exponential family,
such as aster models -- contributed package aster) and what to do when it
does not.
This suggests many changes to glm, glm.fit, predict.glm,...

Apparant bug in binomial model in GLM (PR#13434)

Submission from: (NULL) (192.38.46.92)
There appear to be a bug in the estimation of significance in the binomial model
in GLM. This bug apparently appears when the correlation between two variables
is to strong.
Such as this dummy example
c(0,0,0,0,0,1,1,1,1,1)->a
a->b
m1<-glm(a~b, binomial)
summary(m1)
It is sufficient that all
