Please could someone kindly review this patch for me?
Many thanks

[LLVMdev] [lld] Patch to incorporate lld test-suite into "make check-all"
Hi again,
Any interest in this patch to incorporate lld testing into "make check-all"
when lld built as part of llvm? Is this the best place to post patches for
lld?
I've attached it again here to include a missing dependency.
Cheers
Andy

rtmvt
I have been using the rtmvt function in the {tmvtnorm} package i'm getting
the warning:
"Acceptance rate is very low and rejection sampling becomes inefficient.
Consider using Gibbs sampling."
but i AM specifying the gibbs algorithm!!:

R_qsort_int_I() error
Hi,
I want to use R_qsort_int_I() in my C function, but getting the
following error. It looks like there is a conflict between Rmath.h,
which I use to generate random numbers, and R_ext/Boolean.h I would
appreciate any help to fix this problem.

about MCMC pack again...
Hello, thank you very much for your previous answers about the C++ code.
I am interested in the application of the Gibbs Sampler in the IRT
models, so in the function MCMCirt1d and MCMCirtkd. I've found the C++
source codes, as you suggested, but I cannot find anything about the
Gibbs Sampler. All the files are for the Metropolis algorithm.
Maybe I am not able to read them very well, by the

Question about checkTmvArgs function in rtmvnorm (package tmvtnorm)
Hello!
I was wondering if it's possible to see the actual code of
checkTmvArgs function that is part of the code for rtmvnorm (which is
below - I just typed "rtmvnorm" on the prompt). I get an error:
Error in checkTmvArgs(mean, sigma, lower, upper) :
sigma must be a symmetric matrix
At the same time I am pretty sure that the matrix I am passing as
sigma is a var-covar matrix

sampling from Laplace-Normal
Hi,
I have to draw samples from an asymmetric-Laplace-Normal distribution:
f(u|y, x, beta, phi, sigma, tau) \propto exp( - sum( ( abs(lo) +
(2*tau-1)*lo )/(2*sigma) ) - 0.5/phi*u^2), where lo = (y - x*beta) and
y=(y_1, ..., y_n), x=(x_1, ..., x_n)

same initial data for all parameters. I

initial points for arms in package HI
Dear R-users
I have a problem choosing initial points for the function arms()
in the package HI
I intend to implement a Gibbs sampler and one of my conditional
distributions is nonstandard and not logconcave.
Therefore I'd like to use arms.
But there seem to be a strong influence of the initial point
y.start. To show the effect I constructed a demonstration
example. It is reproducible

Have you ever experienced this problem with REAL in a C code
Dear all,
I'm currently experiencing big troubles with my C code called by .Call
in a R function.
I know this may not be the right place for such things but these errors
are driving me crazy. And I hope other people may have already
experienced these problems so that they could give me good suggestions.
Sorry if I'm completely out of topic.

Gibbs sampler...did it work?
I am writing a Gibbs sampler. I think it is outputting some of what I want,
in that I am getting vector of several thousand values (but not 10,000) in a
txt file at the end.
My question is, is the error message (see below) telling me that it can't
output 10,000 values (draws) because of a limitation in my memory, file
size, shape etc, or that there is an error in the sampler itself?

Which BUGS should one use?
Hello ALL!
Some times ago I started to learn and play with Bayesian stuffs. Many
advice use of WinBUGS for Bayesian inference Using Gibbs Sampler.
However, WinBUGS is discontinued, and now, development is under
OpenBUGS. I wasn't lazy, so I installed both and tried out. In more than
90% of cases they give comparable outcome. But in few cases I got
substantial differences. Recently, I read nice

RE: Polycom buddies question
A follow up (late better than never)
Finally had time to sit down and look at this
sip.cfg
<keys key.scrolling.timeout="1"
key.IP_500.31.function.prim="BuddyStatus"/>
This turns the Services key which I never use on a 501 into the Buddy
Status. It even works while on a call. One touch!

multivariate Stochastic Volatility and GARCH
Dear everyone,
i`m a german economics student, writing my master´s thesis about
"Multivariate Volatility Models". After having read about theoretical
aspects of Multivariate GARCH ans Stochastic Volatility Models, I would like
to compare DCC-GARCH and DC-SV with help of an empirical application. I
figuered out that one has to use MCMC-simulation-methods for that. Some days

I remember finding the same thing (although I haven't tried it on a recent

deflexion exercise?
I read the Ed Gibbs blog posting on BDD, and there was a reference to
implementing the game Deflexions as a way of learning about
expectations...
I''d like to do this exercise, can you provide me with the details
(starting points, objectives, etc...)
Thanks!
