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.
I'm using the R

multinomial choice modeling with mlogit
Hi all,
Does anyone knows how to handle ordered preferences applying the R
package mlogit (multinomial logit model)? My data set provides for each
customer preferences (given as percentages) for 6 different brands. I
would like to use for model calibration not just that brand with
maximum stated preference.
I know that ordered preferences can be used in the R package MNP

multinomial logit discrete choice model
Hi,
I'm struggling trying to specify a multinomial logit discrete choice model
in R.
Any help and/or code examples appreciated.
I am specifically interested in specifying a model where no universal choice
set exists and each choice set has a variable number of alternatives (one of
which is chosen) see data below.
Many Thanks,
David

Multinomial MCMCglmm
Thanks for your answers Stephen and Ben,
I hope I am posting on the correct list now.
I managed so far to run the multinomial model with random effect with the
following command:
MCMCglmm(fixed=cbind(Apsy,Mygl,Crle,Crru,Miag,empty) ~
habitat:trait,random=~idh(trait):mesh,family="multinomial12",
data=dataA,rcov=~trait:units)

Multinomial Nested Logit package in R?
Dear R-Help,
I'm hoping to find a Multinomial Nested Logit package in R. It would
be great to find something analogous to "PROC MDC" in SAS:
> The MDC (Multinomial Discrete Choice) procedure analyzes models
> where the
> choice set consists of multiple alternatives. This procedure
> supports conditional logit,
> mixed logit, heteroscedastic extreme value,

multinomial regression model
Hi,
Consider the need for a regression model which can handle an ordered
multinomial response variable. There are, for example, proportional odds
/ cumulative logit models, but actually the regression should include
random effects (a mixed model), and I would not be aware of multinomial
regression model as part of lme4 (am I wrong here ?). Further, the
constraint of proportional odd models

R function for computing Simultaneous confidence intervals for multinomial proportions
Dear all,
Does someone know an R function implementing the method of Sison and
Glaz (1995) (see full ref below) for computing Simultaneous confidence
intervals for multinomial proportions?
As alternative method, I think to boostrap the mean of each proportion
and get in that way confidence interval of the mean.
I observed 21 times a response that could be one out of 8 categories

multinomial analisys
Hi, i'm an italian student that use for the first time the mailing list. I need an help to use a function for elaborate a multinomial logit analisys. I'm making a paper on the USA's commons and their way of organize their service. The various tipologies of service are 4: public, contracting in, contracting out and no-profit. I have 10 different service for each common, and for each

Questions about use of multinomial for discrimination.
Dear All,
I am looking at discriminating among several individuals based on a few
variable sets (I think some variables do not make sense unless they are
entered together, so I "force" them into the models together, hence
datasets). I have done so with linear discriminant analysis (LDA) using
"MASS::lda", with acceptable results. However, one of my collaborators

error message when downloading packages using the OS X shell
Hi Fellow R Users,
I recently upgraded to Mac OS X 10.5 (Snow Leopard) and had some issues
downloading and running R 2.10.1. I fixed the tcl/tk problem I was
originally having but it was replaced with another. I run R out of the shell
(terminal) and when I ask it to download.packages() it gives me the
following message:

Rounding multinomial proportions
I present you with a function that solves a problem that has bugged me for
many years. I think the problem may be general enough to at least consider
adding this function, or a revamped version of it, to the 'stats' package,
with the other multinomial functions reside.
I'm using R to export data to text files, which are input data for an
external model written in C++. Parts of the

multinomial logit estimation
Good morning,
I'd like to estimate a simple multinomial logit model in R (not a McFadden conditional logit). For instance, I'd like to estimate the probability of someone having one of eight titles in a company with the independent variables being the company characteristics. A binary logit is well documented. What about the multinomial?
Thanks,

logistic regression: categorical value, and multinomial
I have two questions:
1. If I want to do a binomial logit, how to handle the
categorical response variable? Data for the response
variables are not numerical, but text.
2. What if I want to do a multinomial logit, still
with categorical response variable? The variable has 5
non-numerical response levels, I have to do it with a
multinomial logit.
Any input is highly appreciated! Thanks!

multinomial logistic regression
Hi, how can I do multinomial logistic regression in R?
I think glm() can only handle binary response
variable, and polr() can only handle ordinal response
variable. how to do logistic regression with
multinomial response variable?
Thanks

How to get predicted marginal (aka predicted mean) after multinomial logistic?
I tried to use the effect() to get predicted marginals for multinomial
logistic as I did for general logistic regression, but failed. Is there
anyway to do that?
Thx!

Generating multinomial distribution and plotting
I have had plenty of succes generating one dimensional variables and plotting
them, but what do i do for more (specifically 2) dimensional multinomial
variables?
I figure i have to create a vector consisting of two 1 dim normallly
distributed variables, that way i can also control the correlation.
But how do i do this :) ?
Many thanks

does multinomial logistic model from multinom (nnet) has logLik?
I want to get the logLik to calculate McFadden.R2 ,ML.R2 and
Cragg.Uhler.R2, but the value from multinom does not have logLik.So my
quetion is : is logLik meaningful to multinomial logistic model from
multinom?If it does, how can I get it?
Thank you!
ps: I konw VGAM has function to get the multinomial logistic model
with logLik, but I prefer use the function from "official" R

Method for selection bias with multinomial treatment
I have to the treatment effect base on the observational data.And the
treatment variable is multinomial rather than binary.Because the
treatment assignment is not random,so the selection-bias exists.Under
this condition,what's the best way to estimate the treatment effect?
I know that if the treatment is binary,I can use propensity score
matching using MatchIt package.But what about

Yes. I could stop there but you shouldn't. The author of the package
provides plenty of examples (and two good vignettes) showing you how to do
this. Suggest you do some work in that area. Look especially at how model

Latent class multinomial (or conditional) logit using R?
Hi everyone?
Does anybody know how can I estimate a
Latent class multinomial (or conditional) logit using R?
I have tried flexmix, poLCA, and
they do not seem to support this model.
thanks in advance
