How can I measure the difference between 2 models?
Dan Griffith in hi
Dan Griffith in his book (the
Introduction) “Advanced Spatial Statistics” explained exactly how
to deal with this problem. You can not use the mean since mean is not a
sufficient statistics and also it is easy to prove that the mean is not an
efficient statistics.

The new SAS macro "glimmix" can do it easily. It is designed for generalized
linear model(include logistic regression) with spatial information.

still there.
In this case, you need to incorporate the
spatial dependence (described by variogram) into the ttest. Try the generalized
least square for a likelihood approach.

To add to this discussion, one of Peter MacDonald's students changed MIX to
Rmix using the Free R-package with nlm for the mle optimization. So it is
free(but it is good for Peter if you want to spend some money to buy MIX)
and excellent for mixture population from my view.
As for plateau/kinks/br
I think the SAS procedure "proc mixed" can do all of these.

Hi people:
I am looking for information (journa
Hi, all:
I would appreciate your comments on following approach:
Suppose that I have n data points s(l), l =1,..n.
If I like to test whether the mean is zero, traditionally I would take the
sample mean, sbar, and sample variance, say sigma1sbar, to use the t-test,
such as t=sbar/sigma1sbar.
