FEERCI: A python package for EER confidence intervals

Project description

FEERCI: A Package for Fast non-parametric confidence intervals for Equal Error Rates

**FEERCI** is an opinionated, easy-to-use package for calculating EERs and non-parametric confidence intervals efficiently. It offers a single method, ``feerci.feerci``, that returns both an EER and CI for provided impostor and genuine scores. The only dependency is numpy.

``pip install feerci``

What's New
- Switched output arguments around, to make more intuitive sense
- Initial release of package

**FEERCI** is distributed under the MIT license


Calculating just an EER::

import feerci
import numpy as np
impostors = np.random.rand(100)
genuines = np.random.rand(100)
eer,_,_,_ = feerci.feerci(impostors,genuines,is_sorted=False,m=-1)

Calculating an EER and 95% confidence interval::

eer,ci_lower,ci_upper,bootstrapped_eers = feerci.feerci(impostors,genuines,is_sorted=False)

Calculating an EER and 99% confidence interval::

eer,ci_lower,ci_upper,bootstrapped_eers = feerci.feerci(impostors,genuines,is_sorted=False,ci=.99)

Calculating an EER and 99% confidence interval on 1000 bootstrap iterations::

eer,ci_lower,ci_upper,bootstrapped_eers = feerci.feerci(impostors,genuines,is_sorted=False,m=1000,ci=.99)
