Dear R users, I´m studying about Bayesian Statistics. In this context, please, anyone have some basic script of RJMCMC (Reversible Jump Markov chain Monte Carlo) in R or WinBUGS? My aim is to learn how to implement this methodology. Thanks a lot. Marcus Vinicius [[alternative HTML version deleted]]

Hi, Do any body know which packages of R I need to go for the below topics? 1. Monte Carlo Markov chain (MCMC) 2. Gibbs Sampling 3. Metropolis Hastings Thanks in advance... Shubha [[alternative HTML version deleted]]

Dear Wine-friends, I was wondering if any of you would have a clue around why WinBUGS (http://www.mrc-bsu.cam.ac.uk/bugs/), a nifty Markov chain Monte Carlo sampler widely used in Bayesian statistical modelling, no longer works when run through any version of WINE newer than 1.1.12. I have encountered this issue of my machines at home (which runs on Zenwalk 6.0) and work (Mandriva 2008.1) a

Dear list users, I need to learn about MCMC methods, and since there are several packages in R that deal with this subject, I want to use them. I want to buy a book (or more than one, if necessary) that satisfies the following requirements: - it teaches well MCMC methods; - it is easy to implement numerically the ideas of the book, and notation and concepts are similar to the corresponding R

h?, I am preparing undergraduate thesis If you help me this would make me feel good. First I need to analyze effect of Dow Jones Industrial average(DJIA)'s return on Istanbul Stock Exchange(ISE). I want to use Markov-Switching Bayesian Vector Autoregression Models (MSBVAR) that is used to examine the effect of a large economy?s stock exchange movement on a small economy?s stock exchange

R Community - I am attempting to fit a model as described in Hampton, Bossaerts, and O'doherty (J. Neuroscience) 2006. They use a bayesian hidden markov model to model the Reversal Learning data. I have tried using HMM and depmixS4 with no success. My data is a Reversal Learning Task in which there are 3 sets of patterns over 3 blocks. The participant receives incorrect or correct

We were promised this package last spring but I can't find it anywhere! Does anyone have any info? Thanks. >From RNews: "Umacs (Universal Markov chain sampler) is an R package (to be released in Spring 2006) that facilitates the construction of the Gibbs sampler and Metropolis algorithm for Bayesian inference ..." -- View this message in context:

hi there! how u doin?...hope fine. look, i've a difficulty in simulation especially for the bayesian analysis using R. Using the famous Markov Chain Monte Carlo (MCMC) method, Methropolis hasting algorithm i want to simuate different distrbution like: 1/ Weibull-exponential 2/Gamma-Gamma 3/Poisson-Gamma 4/Normal-Normal 5/Normal-Gamma 6/ Negative binomial - Jeffrey's prior Especially, i

Thanks to those who responded to my inquiry about generalized linear mixed models on R and S-plus. Before I summarize the software, I note that there are several ways of doing statistical inference for generalized linear mixed models: (1)Standard maximum likelihood estimation, computationally intensive due to intractable likelihood function (2) Penalized quasi likelihood or similar

Hi, I think I have configured everything correctly but for some reason I can?t get a list of the shared mailboxes to show up. When I run: doveadm acl debug -u m.markov Shared/d.marteva/INBOX doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually

Hello, I am a chemical student and I make use of 'lme/lmer function' to handle experiments in split-plot structures. I know about the mcmcsamp and I think that it's very promissory. I would like knowing "the concept behind" of the mcmcsamp function. I do not want the C code of the MCMCSAMP function. I would like to get the "pseudo-algorithm" to understanding that

Dear All, I am having trouble getting an R package to build and install correctly under Windows. In this package, which builds and checks OK under Linux, I use zlib (among other functions, gzprintf). As mentioned by Prof. Ripley a while back, the file "CHANGES" under src/gnuwin32 says explains that to, to use zlib, one has to set $(ZLIB_LIBS) in PKG_LIBS. I have a Makefile.win with

I don?t seem to have that install on my Debian machine. But I have done this: 1 LIST "" % * LIST (\HasNoChildren) "/" confirmed-spam * LIST (\HasChildren) "/" Archive * LIST (\HasNoChildren \Sent) "/" Sent * LIST (\HasChildren \Trash) "/" Trash * LIST (\HasNoChildren) "/" Spam * LIST (\HasChildren) "/" Archives * LIST

I have a Samba as Primary Domain Controller, and a Windows 2003 Server machine that joins to the Domain, but when i reboot i cant log in. I receive a message like: Cant login, the Doiman Controller is not avaiable or unreachable. Thus i cant login to the domain. I know the win2003 machine can see the Samba Machine 'cause i can use the shares, it is not a problem of the users, i have added and

I have downloaded the Umacs (Universal Markov chain sampler) and submitted the following sample code from Kerman and Gelman.   s <-Sampler( J=8, sigma.y  =c(15,10,16,11,9,11,10,18),           y  =c(28, 8,-3,7,-1,1,18,12),      theta =Gibbs(theta.update,theta.init),           V =Gibbs(V.update,mu.init),         mu =Gibbs(mu.update,mu.init),         tau =Gibbs(tau.update,tau.init),

Thank you for your prompt answer. The breathing signal observations are the amplitude values as a function of time and phase. According to our model the hidden states are the different breathing types. Subjects, whose respiratiion process is regular, are likely to breathe, keeping the same cycle pattern/type, for many consecutive cycles. therefore dwelling in the same hidden state. The more

Dear Users, i have this time series, the tree lines means different level, i would use a Markov switching model with two states to modelling this time series. i would obtain the relative transition matrix (2X2) the first state is above the value of 23.65 (the higher line) the second state is below the value of 23.65 You can ignore the other two lines

Greetings fellow R entusiasts! We have some problems converting a computer routine written initially for Gauss to estimate a Markov Regime Switching analysis with Time Varying Transition Probability. The source code in Gauss is here: http://www.econ.washington.edu/user/cnelson/markov/programs/hmt_tvp.opt We have converted the code to R, and it's running without errors, but we have some

Hi, I am looking for a package to estimate regime switching models (states following a markov chain). I found packages for Hidden Markov Models but I am looking for something a little different: In the HMM the conditional distribution of the observations (give the state) is a known distribution (normal or others), while the package I need should allow to set a conditional distribution (given the
