var-covar matrices comparison:
Hi,
Using package gclus in R, I have created some graphs that show the
trends within subgroups of data and correlations among 9 variables (v1-v9).
Being interested for more details on these data I have produced also the
var-covar matrices.
Question: From a pair of two subsets of data (with 9 variables each, I
have two var-covar matrices for each subgroup, that differ for a
treatment on one

comparing glm models - lower AIC but insignificant coefficients
Hello,
I am a new R user and I am trying to estimate some generalized linear
models (glm). I am trying to compare a model with a gaussian
distribution and an identity link function, and a poisson model with
a log link function. My problem is that while the gaussian model has
significantly lower (i.e. "better") AIC (Akaike Information
Criterion) most of the coefficients are not
