reduced set of alternatives in package mlogit
code? example data? We can only guess based on your vague post.
"PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code."
Moreover, this sounds like a statistical question, not a question
about R programming, and so might be more appropriate for a
statistical list like stats.stackexchange.com .

reduced set of alternatives in package mlogit
Hi Jose,
You're referring to your response variable when you're saying it's missing
some of the choices, right? Are your response choices ever known or do they
just occur with extremely low frequency? Either way, I think the mlogit
package would be inappropriate for you. I imagine you would have much
better luck using MCMCpack or writing a model with rstan or something
Bayesian.

mlogit and model-based recursive partitioning
Hello:
Has anyone tried to model-based recursive partition (using mob from package
party; thanks Achim and colleagues) a data set based on a multinomial logit
model (using mlogit from package mlogit; thanks Yves)?
I attempted to do so, but there are at least two reasons why I could not.
First, in mob I am not quite sure that a model of class StatModel exists for
mlogit models. Second, as

fitting multinomial logistic regression
Sir,
I want to fit a multinomial logistic regression in R.I think mlogit() is the
function for doing this. mlogit () is in packege globaltest.But, I can not
install this package. I use the following:
install.packages("globaltest")
Can you help me?

Question about 'logit' and 'mlogit' in Zelig
I'm running a multinomial logit in R using the Zelig packages. According to str(trade962a), my dependent variable is a factor with three levels. When I run the multinomial logit I get an error message. However, when I run 'model=logit' it works fine. any ideas on whats wrong?

mlogit
I am trying to follow this example for multinomial logistic regression
http://www.ats.ucla.edu/stat/r/dae/mlogit.htm
However, I cannot get it to work properly.
This is the output I get, and I get an error when I try to use the mlogit
function. Any ideas as to why this happens?

Multinomial Logit Model with lots of Dummy Variables
Hi All,
I am attempting to build a Multinomial Logit model with dummy variables of
the following form:
Dependent Variable : 0-8 Discrete Choices
Dummy Variable 1: 965 dummy varsghpow at student.monash.edu.augh@gp1.com
Dummy Variable 2: 805 dummy vars
The data set I am using has the dummy columns pre-created, so it's a table
of 72,381 rows and 1770 columns.
The first 965 columns represent

Likelihood Function for Multinomial Logistic Regression and its partial derivatives
Hi,
I would like to apply the L-BFGS optimization algorithm to compute the MLE
of a multilevel multinomial Logistic Regression.
The likelihood formula for this model has as one of the summands the formula
for computing the likelihood of an ordinary (single-level) multinomial logit
regression. So I would basically need the R implementation for this formula.
The L-BFGS algorithm also requires

Multinomial Logit Regression
Hi all,
I have a dataset with a response variable with three categories (1, 2, 3)
and a lot of continuous variables. I'd like to make a MLR with these
variables. I've been watching the libraries nnet and zelig for this purpose
but I don't understand them well.
I use a training sample data to make the MLR.
train.set <- sample(1:1000,1000*0.7)
I have done this:

Stepwise model comparisons for mlogit
I am trying to perform a backwards stepwise variable selection with an mlogit model. The usual functions, step(), drop1(), and dropterm() do not work for mlogit models.
Update() works but I am only able to use it manually, i.e. I have to type in each variable I wish to remove by hand on a separate line.
My goal is to write some code that will systematically remove a certain set of variables

length of variable in mlogit
Dear all,
does anybody have experience with building logits in Mlogit?
I want to test the use of a couple of alternative specific variables with a
generic regression coefficient. However, one of them simply does not work. R
says the length of this variable is different.
Problem: If I check the length of this special variable, I get a value,
which also other variables have ? and with those, the

Fwd: multinomial regression for clustered data
Hello dear R-users,
does any of you know a way to perform a multinomial regression with
clustered data (i.e. repeated measurements)? I made the first analysis with
Stata option vce cluster in the mlogit command but was looking for a similar
functionality in R too...
thanks all!

datasets para regresión logística binomial y multinomial
Buenas.
Sé que en R hay multitud de datasets y me haría falta alguno que
trataran de variables relacionadas con salud, sobre todo para aprender
más acerca de cómo realizar una regresión logística binomial o multinomial.
Gracias..

Mixed multinomial logit model (mlogit script)
Dear all,
I am trying to run a mixed multinomial logit model in R since my response variable has 4 non-ordinal categories. I am using the package mlogit that estimates the parameters by maximum likelihood methods. First of all, I prepared my data using the mlogit.data command. In the mlogit command, one can introduce alternative-specific (fixed factors??) and individual-specific (random
