What you're doing makes no sense. Given p-values p_i, i=1...n, resulting
from hypothesis tests t_i, i=1...n, the q-value of p_i is the expected
proportion of false positives among all n tests if the significance level
of each test is α=p_i. Thus a q-value is only defined for an observed
p-value.

Tahnk you. But, when I try the command you both suggested I get a NULL
as the results.
names(object1 @ x.values)
NULL
Where did I go wrong?

But, since I'm new to GLM, I owuld greatly appreciate how you/others
go about and test the validity of a GLM model.

Hello,
Are there any
couple of days. However, their section on
using R for validating the assumptions is very lacking. Naturally
links like google.com and amazon.com will eventually get me there, but
if somebody have other recommendations, I would be very fortunate to
get even more help.

Hello,
Are there any packages/functions available for testing the assumptions
underlying assumptions for a good GLM model? Like linktest in STATA
and smilar. If not, could somebody please describe their work process
when they check the validity of a logit/probit model?
Regards,

Hello,
silly question I suppose, but somehow I can't manage to extract the
probabilities from a glm.predict() result:
str(res)
Named num [1:9] 0.00814 0.01877 0.025 0.02941 0.03563 ...
- attr(*, names)= chr [1:9] 1 2 3 4 ...
I got from:
# A Gamma example, from McCullagh Nelder (1989, pp.
the shared memory segments have been
deleted.
Thanks,
Matt

,
but in the meantime you may want to post your sessionInfo(). I have
run RcmdrPlugin.IPSUR on R-2.10.1, Windows XP, as recently as
yesterday during class without any problems.
Gotta go for now.

cool.
I will think about it some more. Maybe there is a way to reorganize
it to not confuse students and simultaneously avoid conflicts with
other plugins.
If this doesn't help then I am at a loss without something else like a
sessionInfo().
Cheers,
Jay
