function runif in for loop
Hello,
I'd like to perform a regression using MCMCregress (MCMCpack).
One variable therefore should be a function rather than a variable:
I want to use X as an input and X should be defined as a random number between to values. Therefore I want to use the function runif like:
X <-(1, Xa, Xb) but it seems that runif doesn't allow to use vectors.
So I think I've to calculate the new

MCMC regress, using runif()
Hello,
just to follow up a question from last week. Here what I've done so far (here an example):
library(MCMCpack)
Y=c(15,14,23,18,19,9,19,13)
X1=c(0.2,0.6,0.45,0.27,0.6,0.14,0.1,0.52)
X2a=c(17,22,21,18,19,25,8,19)
X2b=c(22,22,29,34,19,26,17,22)
X2 <- function()runif(length(X2a), X2a, X2b)
model1 <- MCMCregress(Y~X1+X2())
summary(model1)
but I am not sure if my X2-function is

MCMCpack: Selecting a better model using BayesFactor
Dear R users,
Thanks in advance.
I am Deb, Statistician at NSW Department of Commerce, Sydney.
I am using R 2.9.1 on Windows XP.
This has reference to the package “MCMCpack”. My objective is to
select a better model using various alternatives. I have provided here
an example code from MCMCpack.pdf.
The matrix of Bayes Factors is:

Help to understand an Error using summary to an mcmc object
Hi,
I used the MCMCirtKd function of MCMCpack:
posterior2 <- MCMCirtKd(data, dimensions = 2,
+ burnin = 5000, mcmc = 50000, thin = 10,
+ verbose = 10000, B0 = .25, store.item = TRUE, item.constraints =
beta.constraints)
And after apply the comand summary() I got some erros and warnings that I
could not understand:

about MCMC pack
Hello,
I tryed to use the MCMC pack, particularly the function MCMCirtKd to

Effect size of comparison of two levels of a factor in multiple linear regression
Dear R users,
I have a linear model of the kind
outcome ~ treatment + covariate
where 'treatment' is a factor with three levels ("0", "1", and "2"),
and the covariate is continuous. Treatments "1" and "2" both have
regression coefficients significantly different from 0 when using

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

Parameterization of Inverse Wishart distribution available in MCMCpack and bayesm libraries
Hello Everyone
Both the MCMCpack and the bayesm libraries allow us to make draws from the
Inverse Wishart distribution.
But I wanted to find out how exactly is the Inverse Wishart distribution
parameterized in these libraries.
The reason I ask is the following:
Now its generally standard to express Inverse Wishart as IW(0.5 * DOF,0.5*
Scale). (DOF-> Degree of freedom, Scale -> Scale

Hi,
I have a dataset with the binary outcome Y(0,1) and 4 covariates (X1,X@,X#,X$). I am trying to use MCMClogit to model logistic regression using MCMC. I am getting an error where it doesnt identify the covariates ,although its reading in correctly. The dataset is a sample of actual dataset. Below is my code:

riwish() problem
R users-
In moving from R 2.0.0 to R 2.1.0 in Windows, I have encountered a problem
with the "riwish" command in the package "MCMCpack". I've searched the
documentation and can't seem to figure it out. For example:
Define a matrix:
> lam <- matrix(c(.00233,-.00057,-.00057,.00190),2,2)
and then use the riwish command to generate a random inverse-Wishart

MCMC for sampling from ordinal logistic regression
Hi:
Is there a R-function that can generate samples from the posterior distribution of an ordered logistic regression model (just like MCMCoprobit from MCMCpack in R). I will greatly appreciate some guidance in this regard.

Extended Hypergeometric Distribution

There exists a non-central hypergeometric distribution function in the (MCMCpack) package, and a hypergeometric distribution function in the (stats) package.
Is there a function for sampling from an extended hypergeometric distribution?

Add a string to each string of an array
Dear all,
I have an array of strings
a <- c("2008q3","2005q1","2004q3")
I would like to add to each a[i], with i = 1,2,3
the following string "IMT",
such that in the end I could get
b <- c("IMT2008q3","IMT2005q1","IMT2004q3")
Is it possible to accomplish this without a loop command?
Thank you.
Best,
