Markov and Hidden Markov models
Hi,
Is there a package that will estimate simple Markov models and hidden
Markov models for discrete time processes in R?
Thanks in advance,

Package for Markov (Regime) Switching (ARMA) Models
Hello R-Users
Is there a package in R, that handles Markov (Regime) Switching (ARMA) Models for time series modelling and prediction?
Thank you very much.

hidden markov models
Dear R community,
I am looking for an R package or other software to study hidden
Markov models. I need to be able to incorporate multivariate
emissions and covariates for the transition probabilities. The msm
package seems almost perfect for my purpose, but I do not think it
allows multivariate emissions.
I will be grateful for your suggestions.
All the best,

Hidden Markov model in R: books or tutorial biomed/ecology slant
Hi,
I was just wondering if there are any books on R that have applications
using Hidden Markov models
or anyone with tutorials/exercises that can be shared.
Ideally, these would have a bio/ecological slant though not neccesarily.
Any suggestions would be appreciated.
Thanks!

spatial markov chain methods
Hello,
can any one point me to R-packages (if available) which include spatial
Markov Chain methods?
My second question is more general but hopefully not OT: Currently we
are using the software TPROGS, which let people simulate property
distributions in space by some Markov Chain approaches. We face some
problems due to the lack of information between distances of samples
along borehole path

hmm.discnp hidden markov model
Hi all,
I am using a discrete Hidden Markov Model with discrete observations in
order to detect a sequence of integers. I am using the "hmm.discnp" package.
I am using the following code:

Hi, friends!
Has R estimation (library, for example) to do estimation in HMM?
Thanks in advance,

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

multivariate markov switching
Dear helpers,
Does anyone know about a package or a function that allows to estimate
Multivariate Markov-Switching Models, like MS-VAR as introduced by
Krolzig(1997) with R ?
Thanks a lot!!

programming continuous-time markov model likelihood
Dear all,
I need to estimate intensity and probability matrices by the continuous-time markov model... in a first time I used "msm" and it works perfectly. Nevertheless, I have to do other estimations that need programming the likelihood. Is it possible to see somewhere the likelihood used in the msm package? I have readen the papers about likelihood estimation of continuous-time

The aphid package for analysis with profile hidden Markov models
Hi folks,
I'm pleased to introduce a new package called ?aphid?, for analysis with
profile hidden Markov models in R.
The package contains functions for multiple and pairwise sequence alignment
for both nucleic acids and proteins (preferably in the DNAbin or AAbin
format), model building, parameter optimization (Baum Welch and Viterbi
training), plotting, file import & export,

Does anybody know a function to simulate a Markov chain given a
probability transition matrix and an initial state ?

empirical A matrix for dynamic system and markov analyses
I'm working with a dynamic system that I've started to
analyse using msm(I've emailed to chris, orignator of
the program, separately, but maybe he's on holiday).
I'd like to know if anyone has considered the relation
between the markov analysis done with msm on the one
hand, and dynamic system analysis done with MATLAB?
That is, I'm working with a set of empirical data that

markov models with msm
Hello,
I'm working with a dynamic system that I've started to
analyse using msm(I've emailed to chris, orignator of

The data is obtained from a large cohort of students
and consists of a model of learning states that
students pass through over a period of one school
year. As analyzed with the msm program, the data shows

Making a markov transition matrix - more progress
I solved the problem in one more (and more elegant) way. So here's the
program again.
Where does R stand on the Anderson-Goodman test of 1957? I hunted
around and nobody seems to be doing this in R. Is it that there has
been much progress after 1957 and nobody uses it anymore?

# You are holding a dataset where firms are observed for a fixed

generating markov chain
Dear help group,
Just fyi a markov chain is a sequence of transitions between states (say A,T,G,C - on a gene) with a given probability for each transition. In this case there'd be 16 different kinds, each with a different weight.
Given a transition matrix (4x4) filled with all transition probabilities of course, how can I generate a random sequence of a given length, say 200?
