problems with MNP
Hi all,
Does anybody have a hint on what may be going wrong in this R code? I
mimic the sample code from the MNP developers but I seem unable to get the
choice specific variables right.
Thanks,
Joan Serra

Panel MNP
Hi All,
Can the MNP package available in R be used to analyze panel data as well?
*i.e., *if there are 3 observed discrete choices for three time periods for
the same individual , can i estimate a panel multinomial probit model which
allows correlated errors across time periods and individual heterogeneity
(random coefficients) using the MNP package?
In the case that it doesn't work, is

wrong signs using MNP.
Hi,
I recently found the MNP package. Out of curiosity, I tried to reproduce
results from Greene (Econometric Analysis, fourth edition) on page 874.
The signs of the estimates are all opposite those of Greene's table. Might
anyone be able to tell me what I am doing wrong?
I have attached the function call, the coefficients, and a few rows of the
data. The dataset has 210 observations.

MNP - discrete choice experiment
Hello,
I need a little initial help with the MNP package.
I am trying to analyze a discrete choice experiment with the following
settings:
- choice sets consist of 3 alternatives
- choice alternatives are constructed by e.g. two attributes, say brand and
price.
- brand has three levels and price has four levels
- every respondent has to answer 4 different choice sets (drawn randomly or

Files exist, but sometimes are not seen by the clients: "No such file or directory"
Hello all,
We're having problems with files that suddenly stop being seen on the fuse clients.
I couldn't yet find a way to reproduce this. It happens every once in a while.
Sometimes you try to ls some file and it can't be found.
When you run ls on the parent directory, it is shown on the output, and, after that, you can access it.
I'm mentioning ls, but the problem also

Coefficients and Covariances in MNP
Hi everyone,
I use the MNP package to fit my data. I can interpret the coefficients and
covariance. I cannot put them into the original model which is
Wi=Sum(bXij) over j,
Yi(Wi)=0 if max(Wi)<0, j if max(Wi)=Wij>0
j=3 here, 3 choice alternatives, Clio, Punto, Polo
I don't know how to put the coefficients and covariances into W, to
construct W for each j.
The coefficients and

Probit function
Hello,
I want to start testing using the MNP probit function in stead of the
lrm function in my current experiment.
I have one dependant label and two independent varaibles.
The lrm is simple
model <- lrm(label ~ val1 + val2)
I tried the same thing with the mnp function and got an error that I
don't understand
model <- mnp(label ~ val1 + val2)
I get back an immediate error that

ecological meaning of randomForest vegetation classification?
Hi, everyone,
I haven't found anything similar in the forum, so here's my problem (I'm no
expert in R nor statistics):
I have a data set of 59.000 cases with 9 variables each (fractional
coverage of 9 different plant types, such as deciduous broad-leaved
temperate trees or evergreen tropical trees etc.), which was generated by a
vegetation model.
In order to evaluate the quality of

Difference MNP-package and rmnpGibbs from bayesm-package
Hi all,
For my research I have to use a Multinomial Probit model. I saw that
there are two packages, that include a method to estimate my
parameters. The first one is the MNP-package of Imai and van Dyk. The
second one is part of the bayesm-package of Rossi.
The results for both packages are not the same using the same data.
Does anybody know what the difference is between these two approaches?

xen failover
Hi,
I''ve got a question regarding failover.
I''ve set up Xen and DRBD with the versions packaged for CentOS 5.4. Live migration of the domU''s is working between the two xen nodes quite happliy.
Each domU has two LVM LVs associated with it, partitioned as swp and root. DRBD is configured to just sync the LV containing the root partition, not swp.

multinomial probit
Hello All,
I'm trying to run a multinomial probit on a dataset with 28 data
points and five levels (0,1,2,3,4) in the latent choice involving
response variable.
I downloaded the latest mnp package to run the regression. It starts
the calculation and then crashes the rpogram. I wish I could give the
error message but it literally shuts down R without a warning.

Log-likelihood for Multinominal Probit Regression Model
I use mnp to run a multinominal probit regression model, but the summary
doesn't contain the model statistics, such as the log-likelihood and degree
of freedom, for the assessment of the goodness-of-fit of the fitted model.
Is there any way that I can generate these statistics for the fitted model
in R?
Many thanks in advance!

{ARM} IfConversion does not detect BX instruction as a branch
Hi all,
I got a silly bug when compiling our project with the latest Clang.
Here's the outputted assembly:

For the code to execute correctly, either the _ldr_ should be a _ldrne_
instruction or the _ldreq_ instruction should be removed. The error

[PATCH] pmu/fuc: don't use movw directly anymore
fixes compilation issues with recent envytools, because movw was removed
from fuc5, because it doesn't exist there anymore. The current code is
most likely broken for fuc5 hardware as well and might have triggered all
kinds of random memory reclocking fails.
Changes in fuc3 binaries are tue do opcode optimizations using shorter
opcodes when possible.
