State space AR models in R: some examples
Hi all,
Does anyone have an example of an autoregressive (AR) time-series model
specified as a state space model in R? That is, I want to go beyond the
locally linear (constant) model, and fit the following Gaussian AR state
process model:
Xt = a + (1+b)*Xt-1 + epsilon
,where the model for the observation process is
Yt = Xt + tau
I have information of the tau's (observation variance)

How to get prediction for a variable in WinBUGS?
Dear all,I am a new user of WinBUGS and need your help. After running the following code, I got parameters of beta0 through beta4 (stats, density), but I don't know how to get the prediction of the last value of h, the variable I set to NA and want to model it using the following code.Does anyone can given me a hint? Any advice would be greatly appreciated.Best

WinBUGS Question
Hi:
Is there a way we can set up WINBUGS to run 100 simulated datasets on the
same model and output results? Or do we have to call in each dataset at a
time and repeat the process 100 times manually?
Thanks

R2WinBUGS sending variables as factors
Hello R and BUGS users,
I am writing a heirarchical model in R to send to BUGS via R2WinBUGS and
I am finding it difficult to get the model to run. I seem to be having
two problems.
1) I can't seem to send variables classed as factors (Month), is there a
way do this?
2) Checking the Log in WinBUGS I can see that the model is Syntactically
correct, but Bugs is not able to recognise the the

HELP: BRUGS/WinBUGS/RBUGS Response is a combination of random variables
Hi,
Is there anyone know if BUGS language allows the combination of variables as response
such as

Y[i] ~ dnorm(c,d)
It seems doesn't work in my model. The problem is between two ######.

R2WinBUGS problem
Dear friends - I'm on winXP, R 2.71 - I have with some help dveloped
this multivariate normal model, which gives very plausible results in
WinBUGS even without any
initial values specified. However, when I then try to run the same model
via the bugs function in R2WinBUGS with inits specified as inits=NULL
the program stops in a dead end. So I have tried to make inits for the

winbugs - R question
hi all
i would like to use r and winbugs in order to undertake seemingly unrelated regression. i am using the R2WINBUGS library. i just simulated a simple example (sample size is 25) in order to get the correct code.
i suspect that the problem is in my definition of the prior. it wants a multivariate node.
the example could be extended by including more than 1 X variable in the system of

R2winBUGS & WinBUGS gui
I am trying to figure out if it is possible to run winBUGS from within
R, using R2winBUGS, without having winBUGS spawn any windows (basically
- 'true' batch - no GUI actions at all). The reason being I have a
machine which I (and several others) ssh/telnet into, and would like to
run winBUGS without having to mount a virtual desktop of any kind.
I've looked through the r2winBUGS

Saving WinBugs log file when using bugs()
Hi,
I am very new to R and Winbugs. I have been provided with a code that runs
Winbugs from R. The code runs 60 different models and I would like to
either save the Winbugs log file for each of these or reproduce the WinBugs
plots which show convergence over the iterations.I can do this by using
Debug=true and saving manually each time but obviously this is very time
consuming.
Many thanks

Are they fully identical: WinBUGS and OpenBUGS; R2WinBUGS and R2OpenBUGS
Hello ALL!
I am running Linux, Fedora 15 64-bits, and R on it. I need to use
WinBUGS and R2WinBUGS, but as far as I read, WinBUGS is closed project,
to be continued with/as OpenBUGS. Thus, I have found R2OpenBUGS on
OpenBUGS Contributed Code (http://openbugs.info/w/UserContributedCode),
not on CRAN. Author(s) states that it is equivalent for R2WinBUGS. I
tried briefly, and realized few minor

question about calling winbugs in R
Dear All:
Do you have any experience on calling winbugs in R enviorment? I uploaded R2winbgus, pktools, BRugs, ect. in order to call winbugs. In the end, I try to use bugs(). The error message still displays that bugs() can not find.
Do you have any similar issue? If so, could you give your advice?
Many Thanks!
