Customized R Regression Output?
Hello R-Experts,
I am facing the problem that I have to estimate several parameters for a lot
of different dependent variables.
One single regression looks something like this:
y = beta0 + beta1 * x1 + beta2 * x2 + beta3 * x1 * x2 + beta4 * x4 + beta5 *
lag(x4,-1)
where y is the dependent variable and xi are the independent ones. Important
to me are the different estimates of betai and their

Metropolis acceptance rates
Is there a way to recover Metropolis-step acceptance rates AFTER
completing posterior draws?
The immediate application is in the probit.bayes and logit.bayes
models used by Zelig... which I believe is merely calling MCMCpack.
So one strategy, to which I am fixing to resort, is to call, say,
MCMClogit with verbose set to mcmc (or mcmc divided by an integer)
and then look at my screen.

Problem in applying conditional looping
Respected All,
I hope you are enjoying good health, I am tring to write a program in R but
could not be very sucessful. My program draws random sample form bivariate
normal distribution and then compute a variable PIJ. For certian samples
some entries of variable PIJ is apearing as negative, which result
in negative variance estimator. I want to introduce a loop in my program
that verify the each

php3 module and security
Hi,
When php3 module is compiled in apache, files in any directory will
be interpreted by the parser and executed. This is a security breach.
There is a way to correct this? Any comments?
Thanks,

about IRT simulation
hello R:
we have a two-parameter IRT simulation code. The goal is to generate a
response matrix.But the "for" part doesn't run. we don't know what is wrong
with it.
Thanks so much~~~

Problem in conditional looping
Respected All,
I am writing a program in R and facing some problem with applying "if statment".
Program first draw random numbers from bivariate normal distribution
then compute variable say Pi and Pij from that sample and
then further computation
.....
.....
.....
In some samples Pij is appearing with negitive sign and ultimately
resulted in an negative variance estimator.

Dear R-Help
Does "The R Package for Multivariate and Spatial Analysis Version 4.0
(Casgrain
and Legendre, 2001)" exist on CRAN and under what name? It supposedly has a
chronological clustering program ,CHRONO, that I would like to use.
Alternatively, I would ask if there is a R based program that performs
chronological clustering?
Thanks

Problem installing packages and weird R site behaviour
Hi,
I tried to install a package using the menu option and was presented a list
filled with NA's.
I then tried visiting the R site and each option on the side bar (eg. CRAN,
Search,FAQ) sends me to the address attached below (NB: I left off the h in
http).
The first problem seems to be related to the second.
Is anyone else experiencing this behaviour and how do I restore normal
behaviour?

Hexidecimal conversion
Help
I can produce the hexidecimal equivalent of a decimal number but I am having
a hard time reversing the operation. I'm good for hex representations to 159
and am close to extending to 2559. The archives are not clear on the
existence of a function for this task. Is there one?
Here is what I have got so far:

glm.poisson.disp versus glm.nb
Dear list,
This is a question about overdispersion and the ML estimates of the
parameters returned by the glm.poisson.disp (L. Scrucca) and glm.nb
(Venables and Ripley) functions. Both appear to assume a negative binomial
distribution for the response variable.

How to calculate errors in histogram values

I'm new to R but I thought this is the most likely place I could get advice or
hints w.r.t the following problem:
I have a series of measurements xi with associated uncertainties dxi. I would
like to construct the probability density histogram of this data where each
density estimate has an associated error that is derived from the dxi. In
other words, for large dxi the
