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.

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 co...

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 coeffici...

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...

Application of R and MNP
Dear all, I'm a new user of R and MNP. Would anybody advise me what I have done wrong to the input or data. When I add the R7, it said that there is an error "SWP:singular matrix". I can add up to R6 only. Copy of the R console is attached for your reference. Thanks. Andy -------------- next part -------------- A non-te...

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(la...

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 co...

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? Kind regards, Tryntsje

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 that's been ported to OS X. Is it possible that there are RAM restrictions and that when something c...

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...

Anova - interpretation of the interaction term
Hi So carrying on my use of analysis of variance to check for the effects of two factors. It's made simpler by the fact that both my factors have only two levels each, creating four unique groups. I have a highly significant interaction term. In the context of the experiment, this makes sense. I can visualise the data graphically, and sure enough I can see that both factors have different

Request: Suggestions for "good teaching" packages, esp. with C code
...nctions in MASS look! I want code with spaces and " <- " rather than everything jammed together with "=". I don't mean to criticize any particular person's code in raising this point. For teaching exemples, where to focus? Here's one candidate I've found: MNP. as far as I can tell, it meets the first 4 requirements. And it has some very clear C code with it as well. I'm only hesitant there because I'm not entirely sure that a package's C code should introduce its own functions for handling vectors and matrices, when some general purpose li...
