mlogit is an R package for estimating models from the logit family

mlogit is an R package which is useful for the estimation for several models of the logit family, e.g.

  • Multinomial logit models
  • Nested logit models
  • Mixed logit models
  • Multinomial probit

If you apply the mlogit package the data has to be reshaped. For running a multinomial regression without reshaping the data you can use the multinom function from the nnet package.

For an overview of functions have a look into the Package vignette.

R gives me the error "contrasts can be applied only to factors with 2 or more levels" running an mlogit model, but all my factors have 2 levels

I have a set of results from a choice experiment that I am trying to analyse using the mlogit function in R. My data set is shown below, where each STR value represents the three choices in a single choice experiment, 'CHOICE' is a binary variable…

Analysing rank-ordered data using mlogit

I am trying to analyse rank-ordered data using a logit model as described here (more specifically the model in 5.1). Right now I am not interested in the effect of any covariates but only want to asses the item specific differences by looking at the…

R latent class multinomial logit model

I am using the flexmix package to estimate latent class multinomial logit models in R. In choice theory, there can be variables associated with the alternative (generic) or that vary with the agent (alternative-specific). The nnet package that…

Binomial Regression "logit" vs "cloglog"

I am using a binomial regression with a categorical factor with 9 levels (named 'treat.group') and sample sizes in each group from 1-8. 1 treatment group has all positive cases (i.e., 1's) - and this creates a estimation problem with the "standard"…

mlogit package fails to recover synthetic mixed logit model

I am generating data from the following synthetic mixed effects model for the utility of agent $h$ choosing transportation mode $j$: $U_{hj} = \beta_{\text{price}} X_{h,\text{price}_j} + \beta_{\text{time}} X_{h,\text{time}_j} + \gamma_h…

Model relation between two rank variables where ranks are nested within subjects in one variable

I have elicited 10 attributes from $N$ subjects. Each subject rank ordered his own 10 attributes from the most to the least important one. I am interested in the relation between the order of elicitation (i.e. was it the 1st, 2nd, etc. elicited…

Multinomial logit: mlogit vs statsmodels

I am doing a comparison between mlogit in R and statsmodels in python and have had trouble getting them to produce the same result. I'm wondering if the difference is a result of libraries or I am specifying something incorrectly. Any help would be…

Rank-ordered data - dealing with increased randomness among lower ranks
