• choicer

  choicer provides implementations of discrete-choice models with a focus on economic applications. Computationally intensive likelihoods are written in C++ and exposed for use with generic optimizers. Special care is taken to handle high-dimensional alternative-specific constants efficiently. Currently supports multinomial logit (MNL), mixed logit (MXL), and nested logit (NL); more models will be added.
