# Unifed

The unifed distribution is the only exponential dispersion family containing the exponential distribution. This repository contains an R package for working with this distribution. stan functions for the unifed distribution are also provided.

An R vignette introducing the unifed distribution and examples of how to use this package can be found at https://oquijano.gitlab.io/unifed/.

## Important Note

The function `unifed.kappa.prime.inverse`

in version 1.0 of the package returns values with the wrong sign when its argument is less than 0.1.

Please update to the current version to avoid this issue.

## Installation

You can install this package directly from CRAN by typing this in your R console.

`install.packages("unifed")`

## Side effects

Note that this package rewrites the `summary`

method from the `glm`

class. This will not break any code you have that uses the `summary`

function since it is simply a wrapper around `stats::summary.glm`

that sets the dispersion parameter equal to 1 when working with a unifed GLM.
