possibly it is a stupid question but after few hours of trying and searching,
perhaps I used the wrong key words, I decided to post it.
I have the output of a glm() of count data (poisson).
I would like to get the prediction error (cross-validation).
cv.glm() does not work with poisson error family data. Or I have to transform
the output error pred. in some way.
are there method especially for glm() with different error families to receive
the model goodness / the model badness?
thanks in advance, Martin
