[R-sig-ME] glm question

[Thierry Onkelinx]

Dear Joaquin,

Your attachments got stripped. It's better to put them somewhere on
line an add a link in your message.

If your problem concerns a glm() then r-help would be a better mailing
list. If it is about glmer() then this mailing list is fine.

Best regards,

To call in the statistician after the experiment is done may be no
more than asking him to perform a post-mortem examination: he may be
able to say what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does
not ensure that a reasonable answer can be extracted from a given body
of data. ~ John Tukey
