documentation bug in (ctest) chisq.test (PR#2346)
chisq.test with simulate.p.value=TRUE uses the Patefield algorithm, this
is not documented, and the original reference is not given, as it ought
to be. The reference is:
Patefield,W. M. (1981) An efficient method of generating r * c tables
with given row and column totals (algorithm AS 159). Applied Statistics
30, 91-97.

Difference in Monte Carlo calculation between chisq.test and fisher.test
Hello all,
I would like to know what the difference is between chisq.test and
fisher.test when using the Monte Carlo method with simulate.p.value=TRUE?
Thank you

patch equalize_2.4.18.patch on multi-processor
(I resend because my previous text is break. sorry..)
I have a question about equalize_2.4.18.patch.
I use a kernel 2.4.25.
And I have multi-processor(Xeon dual) machine.
I had patch equalize_2.4.18.patch file.
And I had check ‘symmetric multi-processing support’ kernel compile option.
When I use that kernel, the system is down.
But, I had not check ‘symmetric multi-processing support’

randomisation
Dear useRs
I am looking for a way to randomise the values within a matrix:
the conditions are that the sums of the rows and the sums of the columns should
remain the same as in the original matrix.
Any help would be appreciated
Cheers

VaR-Monte carlo Simulation, Historic simulation, Variance-Covariance Simulation
Dear R helpers
Suppose I have a portfolio of securities with exposure to Equity, Bonds and Forex (say $ 1000000 each).
Is there any fucntion in R that will help me calculate Value at Risk (VaR) using Monte carlo Simulation , Historic simulation and Variance - Covariance Simulation.
With regards

Monte carlo simulation in fGARCH
I use fGarch package to estimate AR(1)-ARCH(1) process for a vector of returns. Then, using the estimated parameters I want to simulate 10 000 sample paths where each path has the same length as the vector of returns. So the first line of the code is: spec=garchSpec(model=list(ar= 0.440270860, omega=0.000374365,alpha=0.475446583 , mu=0, beta=0))----
The only way I can think of generating 10 000

monte carlo simulation
Dear R user:
I wonder if it is possible to run monte carlo simulation
with dse2 package(MonteCarloSimulations function) using ordinary
differential equation. How do I define the model? Or if there are any
functions which can run monte carlo simulation using ordinary differential
equation. Please give me some comments. Thanks in advance!!

Monte Carlo Simulation in R...
Hi, Dear R users,
I'm wondering if I can do Monte Carlo Simulation in R. My problem is like
this: I know variable X follows Gamma distribution with shape parameter
0.067 and scale parameter 0.008. The sum of the X is 2000. I need R help me
to simulate a vector of X that satisfies both the probability distribution
and the sum. Anyone has a clue to this? Much appreciated.

Metropolis-Hastings Markov Chain Monte Carlo in Spatstat
I'm testing some different formulations of pairwise interaction point processes
in Spatstat (version 1.11-6) using R 2.5.0 on a Windows platform and I wish to
simulate them using the Metropolis-Hastings algorithm implemented with Spatstat.
Spatstat utilizes Fortran77 code with the preprocessor RatFor to do the
Metropolis-Hastings MCMC, but the Makefile is more complicated than any I have

About Qusi-Monte carlo program
Dear Listers;
Does anybody has experience in doing simulation via Qusi-Monte carlo in R or S-plus, if so, could you like to send a small copy of your program to me, I appreciate and thanks in advance!!
Frankly speaking, I am struggling to write this kind of program, while I could not figure out, painful!!!!!
Best regards,
Tony

R package: Mchtest - Monte Carlo hypothesis testing allowing Sequential Stopping
Hi,
This is an announcement for a package that has been up on CRAN since March 2006 but was never announced.
The package is Mchtest - for Monte Carlo hypothesis tests allowing sequential stopping. The idea is to use the sequential probability ratio test boundaries to stop resampling for a Monte Carlo hypothesis test such as a bootstrap or permutation test. This means that you will take many

generating samples by Monte Carlo
Hello Dear,
I am trying to generate samples by using Monte Carlo simulation. For
example,
1000 samples, Exponential distribution (f(x), lambda=0.0005, 0<=x<=360)
Is there any package for Monte Carlo or just use random sample generation
function?
Many thank you for your help in advance,
Jin

monte carlo simulations/lmer
Hi - I am doing some monte carlo simulations comparing bayesian (using
Plummer's jags) and maximum likelihood (using lmer from package lme4
by Bates et al).
I would like to know if there is a way I can flag nonconvergence and
exceptions. Currently the simulations just stop and the output reads
things like:
Error in optim(.Call("lmer_coef", x, 2, PACKAGE = "Matrix"), fn,
