# PyLogit

PyLogit is a Python package for performing maximum likelihood estimation of conditional logit models and similar discrete choice models.

## Main Features

- It supports

   - Conditional Logit (Type) Models

     - Multinomial Logit Models

     - Multinomial Asymmetric Models

        - Multinomial Clog-log Model

        - Multinomial Scobit Model

        - Multinomial Uneven Logit Model

        - Multinomial Asymmetric Logit Model

   - Nested Logit Models

   - Mixed Logit Models (with Normal mixing distributions)

- It supports datasets where the choice set differs across observations

- It supports model specifications where the coefficient for a given variable may be

   - completely alternative-specific   

   (i.e. one coefficient per alternative, subject to identification of the coefficients),

   - subset-specific  

   (i.e. one coefficient per subset of alternatives, where each alternative belongs to only one subset, and there are more than 1 but less than J subsets, where J is the maximum number of available alternatives in the dataset),

   - completely generic  

   (i.e. one coefficient across all alternatives).

## Installation

Available from [PyPi](https://pypi.python.org/pypi/pylogit):

```

pip install pylogit

```

Available through [Anaconda](https://anaconda.org/conda-forge/pylogit):

```

or

```

conda install -c timothyb0912 pylogit

```

## Usage

For Jupyter notebooks filled with examples, see [examples](./examples/).
