Windows binaries for DCluster updated
Hi,
As Frank M. Howell noticed (and probably other users), the Windows
binaries for DCluster I put in my web page are not working... I have
compiled the source code
again and know it does. Please, download it again, and sorry for the
inconvenience.
The URL is http://matheron.uv.es/~virgil/Rpackages/DCluster

bootstrap pValue in DClusters
Hello R-List
I use DClusters package (I work in a cancer regestry). I have 2 questions
about it:
1-how is it possible to get back the bootstrap pValue? I mean the pValue of
the calculated statistic with respect of the distribution of this statistic
under the null hypothesis.
2-how is it possible to test an overdispersion in the poisson model? for
choosing a best model I need this mesure of

Request for help (reference details)
I referred in my reply to a paper by Diaconis and Sturmfels. The exact
reference is:
Diaconis and Sturmfels, Algebraic algorithms for sampling from conditional
distributions, Ann. Stat 26 (1998) 363-397.
They cite the following:
Besag and Clifford, Generalized Monte Carlo significance tests, Biometrika
76 (1989) 633-42.
which actually contains your problem (section 3, Testing the Rasch model)

lme
I am using rw0641.
In my continuing quest to understand repeated measures analysis, I again
return to lme. I exported the Potthoff and Roy data Orthodont.dat from
S-PLUS 4.5 to avoid capture errors and ran the examples in the R help. I
imported the data.frame with
data <- read.table("Orthodont.dat",header=T)
attach(data)
and created the objects

Help on computing Geary's C statistic to test for Spatial Autocorrelation
Dear Users:
I have been trying to use the geary.test() function in *R*, but am having
slight difficulty understanding how I am to apply it in my context.
I have 2 matrices:
1) *n x p* matrix of *n* observations with *p* measurements each. It may be
noted that this matrix has a spatial dimension to it, as the
*n*observations are at different geographical locations on a map.
2) *n x n* spatial

clustering
Hi everybody,
I'm performing a cluster analysis (pkg "cluster") on a
dataset which includes 15 variables: is there a way to
know how much each variable weighs on the final
clustering output?

Newbie Question: Spatial Autocorrelation with R Tutorial?
Howdy All,
I am looking for some good tutorials (books, websites, whatever) for calculating/testing for Spatial Autocorrelation using R.
Specifically, I am wanting to test for autocorrelation of a number of variables measured at a set of discrete locations.
Up to this point I have been exploring the "spdep" package and I can get "moran.test" to work, but I am concerned that

New user...tips for spdep?
Hello List,
I'm a very new user to the R system. I'm only beginning to learn the
basics, but so far I've been able to do little more than try a few examples,
and of course begin reading the documentation.
My primary motivation for exploring R is the availability of tools like the
'spdep' package for calculating spatial statistics such as Geary's C and
Moran's

Extrange behaviour of Gcc-3.3
Dear R users,
I have found a quite uncommon behaviour when compiling a library I want
to call from R (avce00, in package RArcInfo).
I define CPL_LSB (-DCPL_LSB is passed to the compiler in the command
line) but it's useless, since #ifdef CPL_LSB ... #endif clauses doesn't
notice that CPL_LSB is defined. I also set -O2.
Any clue? I have tested the library without optimising the code and

Parallelizing spatial computations
Hi,
I have to run lots of simulations based on several spatial scan
statistics. Since the main overhead is due to a call to 'apply' , I
was wondering whether it could be possible to parallelize this "loop".
I know there are a few packages for parallel computing in R but I don't
know whether it's worth trying them. Have anyone used these packages
before?
I have a linux

How to handle NA-values in raster-based Geary´s C test?
Hi,
I have a question on testing spatial autocorrelation on raster data
including NA-values. In particular, I like to calculate Moran?s I and
Geary?s C indices by using inverse distance weighting matrices.
Calculating Moran?s I with moran.test works fine, because the function
contains the option "na.action=na.pass". Unfortunately, the function
geary.test does not contain this

Maximization of a loglikelihood function with double sums
Dear R experts,
Attached you can find the expression of a loglikelihood function which I
would like to maximize in R.
So far, I have done maximization with the combined use of the
mathematical programming language AMPL (www.ampl.com) and the solver
SNOPT (http://www.sbsi-sol-optimize.com/manuals/SNOPT%20Manual.pdf).
With these tools, maximization is carried out in a few seconds. I wonder

Anscombe-Glynn, Bonett-Seier, D'Agostino
Dear useRs,
I was searching CRAN for implementation of kurtosis and skewness tests,
and found that there is some kind of lack on it.
So, I have written three functions:
1. Anscombe-Glynn test for kurtosis
2. Bonett-Seier test based on Geary's kurtosis (which is not widely
known, but I was inspired by original paper describing it, found
coincidentally in Elsevier database)
3.
