Provides a modified function bic.glm of the BMA package that can be applied to multinomial logit (MNL) data. The data is converted to binary logit using the Begg & Gray approximation. The package also contains functions for maximum likelihood estimation of MNL models.

The main function of the package is bic.mlogit which runs the Bayesian Model Averaging on multinomial logit data. Results can be explored using summary.bic.mlogit, imageplot.mlogit, or plot.bic.mlogit functions.
An MNL estimation of a single model can be done using estimate.mlogit. Use summary.mnl to view its results.
