Thanks for the quick answer, that's what I was thinking too. Just wasn't sure
wether this was a bug or a matter of computations becoming singular.

Dear Jose,
normal mixture clustering (mclust) operates on points times variables data
and not on a distance matrix. Therefore
it doesn't make sense to compute Mahalanobis distances before using
mclust.
Furthermore, cluster analysis based on distance matrices

Here's a very simple function that more literally emulates 'more'. It

be simplified and/or improved.)

How can I define a static member of a class? not a static method,

I started learning data mining by reading his book 'classification and
regression tree'. His paper and website about random forest are the
best resource for my learning in statistics.
It is truly a big loss in statistics. I feel terribly bad.

Since I've seen no replies to your question, I will offer brief
comments that will certainly not meet your needs but might get you
started. I don't know what you mean by a static member of a class. I
just got 3 hits from RSiteSearch(static member of a class), but I
don't know if
RSiteSearch(R-squared for glm) produced 17 hits, the second of
which cited three articles that might interest you
(http://finzi.psych.upenn.edu/R/Rhelp02a/archive/48688.html). Other
comments suggest that the percent of deviance explained may not be
terribly useful (e.g.,
RSiteSearch(GARCH with explanatory variables) produced one
irrelevant hit, but RSiteSearch(GARCH with explanatory variables)
produced 15 hits. Tobias Muhlhofer suggested one could write out the
loglikelihood (and possibly its gradient) which you could then maximise
