Bayesian credible intervals for ratios

bayesint

This repository includes the Python code for calculating Bayesian credible interval of ratios of independent beta distributions. It has been used in Methods for calculating credible intervals for ratios of beta distributions with application to relative risks of premature death during the second plague pandemic

Getting Started

Prerequisites

• Python 2.7+

Installation

Clone the repository then run

python setup.py install

Usage

To get the relative risk of a contingency table given by

	+	_	Total
+	P = 56	M- P	M = 366
-	C = 126	N - C	N = 354
Total	C + P	N - C + M - P	N + M

run

from bayesint import rel_risk
rel_risk(56, 126, 366, 354)
# 236/549

and to obtain the equal-tailed quantile interval for the data given in the contingency table run

from bayesint import eqt_int_frac
eqt_int_frac(56, 126, 366, 354, (0, 0, 0, 0), "risk", 0.05, "estim")
# (236/549, 0.184135819539239, 0.667343920284484)
