indexing model names for AICc table
hi folks,
I'm trying to build a table that contains information about a series of
General Linear Models in order to calculate Akaike weights and other
measures to compare all models in the series.
i have an issue with indexing models and extracting the information
(loglikehood, AIC's, etc.) that I need to compile them into the table.
Below is some sample code that illustrates my

? ALSA ? projext ? start ??
hi guys ! i'd like to know if rhere are allready code snips for a ALSA
wrapper ?
since OSS is realy crappy and i don't have the money for the comerical
ones.
I think the ALSA interface should be there fast, or the OSS driver
should be able to handle the ALSA->OSS(fake) module propper and not
turning into a drum mashine....

Probit regression with limited parameter space
Dear R helpers,
I need to estimate a probit model with box constraints placed on several of
the model parameters. I have the following two questions:
1) How are the standard errors calclulated in glm
(family=binomial(link="probit")? I ran a typical probit model using the
glm probit link and the nlminb function with my own coding of the
loglikehood, separately. As nlminb does not

fixed effect significance_NB mixed models_further pursuit
7 Jan 09
Hello,
I am using R version 2.7.0 in a Windows XP context.
I am also using the glmm.admb package (created by Dave Fournier, Hans
Skaug, and Anders Nielson) to run mixed-effects negative binomial
models.
To the best of my knowledge and ability, I have searched and studied
the R-help, R-sig-mixed models, and ADMB NBMM for R (through Otter

calculates the standard error with the delta method
I need your help because I am having difficulties to finalize an econometric model.By the way, I want to calculate the standard error with delta method in a 2sls model with interactions under R.I want to determine the total effect of the institutions (Institutions + D_MinMond * Institutions) on logYLby summing the estimated parameters of (Institutions) and (D_MinMond * Institutions);D_MinMond is a

p-value for the parameter in ARIMA model with R
Dear All,
I decided to use an AR(1) model for the residual series and trying to find the p-value for each parameter by using arima command in R, but i never find it from the output. The output gives me the parameter and mean's value, its standard error, estaimated variance, AIC and loglikehood, but no p-value is given.
What i did was, i assign the residuals into the 'residual'

GLM output for deviance and loglikelihood
It has always been my understanding that deviance for GLMs is defined
by;
D = -2(loglikelihood(model) - loglikelihood(saturated model))
and this can be calculated by (or at least usually is);
D = -2(loglikelihood(model))
As is done so in the code for 'polr' by Brian Ripley (in the package
'MASS') where the -loglikehood is minimised using optim;

Sequence Prediction
I have a data with the sequence of events with millions records and more than
24 time stamped variables.

Reduce: extra args wishlist?
Is there a reason that Reduce() doesn't take a "..." argument that
would allow arbitrary extra arguments to be passed through to the function?
Here is a little example of how this would be convenient:

cases=0),

power and sample size for a GLM with Poisson response variable
Craig, Thanks for your follow-up note on using the asypow package. My
problem was not only constructing the "constraints" vector but, for my
particular situation (Poisson regression, two groups, sample sizes of
(1081,3180), I get very different results using asypow package compared
to my other (home grown) approaches.

R and Clusters
Dear All,
I hope I am not asking a FAQ. I am dealing with a problem of graph
theory [connected components in a non-directed graph] and I do not
want to rediscover the wheel.
I saw a large number of R packages dealing for instance with the
k-means method or hierarchical clustering for spatially distributed
data and I am basically facing a similar problem.
I am given a set of data which are the

Reading parameters from dataframe and loading as objects
Hi List,
I want to read several parameters from data frame and load them as object
into R session, Is there any package or function in R for this??
Here is example

value <-c(15, 20000, 200000, 0.001, .999)

problem getting R 2.3.1 svn r38481 to pass make check-all
Hi,
I noticed this problem on my home desktop running FC4 and again on my
laptop running FC5. Both have previously compiled and passed make
check-all on 2.3.1 svn revisions from 10 days ago or so. On both these
machines, make check-all is consistently failing (4 out of 4 attempts on
the FC 4 desktop and 3 out of 3 on the FC 5 laptop) in the
p-r-random-tests tests. This is with both default

Multicore/Parallel
I am using the package Multicore/Parallel to do importance sampling. I have
5 cores on my computer. And I have
let's say 10 000 particles to generate. What I did was to send 5 particles
in each time, calling the package parallel. Which means in all I am calling
the parallel command 2000 times.
What happens is in the end somewhere along the way I end up with the error
message error in fork
