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

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

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

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

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

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.

Monte Carlo chisq test
Dear all,
I have a question about the chisq.test command. As an option one can
chose the computation of p-values by Monte-Carlo simulation
(simulate.p.value=T). Is there any documentation available how this
calculations are done and how this simulation based test behaves in
small samples?
Thanks

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,

Monte Carlo simulation in R
Hi, R-helpers,
I'm trying to use R to do a Monte Carlo simulation and need the help. What I
have is a matrix that consists of the probabilities for the persons to
choose zones. For example, in the matrix shown below, each column represents
a person, and each row represents a zone. So, the probability that the first
person will choose the 2nd zone is 30%.
25% 30% 10% 30% 20% 0% 20% 50% 60%

slow loops in Monte Carlo Simulations
Hi there,
I am running Monte Carlo Simulations in R using ordinary "while
(condition)" loops. Since the number of iterations is something like
100.000 and within each iteration a given subsample is extended
sequentially it takes hours to run the simulation.
Does anyone know if there is either a way to avoid using loops in
Monte Carlo Simulations or how to include possible faster

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
