Employing historical records we are able to estimate the risk of premature death during the second plague pandemic, and identify the Black Death and pestis secunda epidemics. We show a novel method of calculating Bayesian credible intervals for a ratio of beta distributed random variables and use this to quantify uncertainty of relative risk estimates for these two epidemics which we consider in a 2 × 2 contingency table framework. 


Frequentist performance of Bayesian confidence intervals for comparing proportions in 2 x 2 contingency tables.
This article investigates the performance, in a frequentist sense, of Bayesian confidence intervals for the difference of proportions, relative risk, and odds ratio in 2 x 2 contingency tables and recommends tail intervals over highest posterior density (HPD) intervals, for invariance reasons.

Exact Bayesian analysis of two proportions
Altham (1969) derived a relation between the cumulative posterior probability for association and the exact p-value in a 2 x 2 table. But she found that, in general, the exact posterior distributionExpand
Monte Carlo Estimation of Bayesian Credible and HPD Intervals
Abstract This article considers how to estimate Bayesian credible and highest probability density (HPD) intervals for parameters of interest and provides a simple Monte Carlo approach to approximateExpand
A Posterior Density for the Difference Between Two Binominal Proportions and the Highest Posterior Density Credible Interval
The statistical inference concerning the difference between two independent binominal proportions has often been discussed in medical and statistical literature. This discussion is far more oftenExpand
Distributions of the ratios of independent beta variables and applications
We establish the exact expressions of X1/X2 and of X1/(X1+X2), where X1 and X2 are independent beta random variables of the first type, and provide some of their applications, in reliability andExpand
The Black Death in London
The Black Death of 1348 - 49 killed millions in its march across Europe, but how many is still a subject of intense debate with claims ranging between 25 and 50 per cent. This book examines theExpand
Human ectoparasites and the spread of plague in Europe during the Second Pandemic
It is shown that human ectoparasites, like body lice and human fleas, might be more likely than rats to have caused the rapidly developing epidemics in pre-Industrial Europe, challenging the assumption that plague in Europe was predominantly spread by rats. Expand
The Black Death: Natural and Human Disaster in Medieval Europe
A fascinating work of detective history, "The Black Death" traces the causes and far-reaching consequences of this infamous outbreak of plague that spread across the continent of Europe from 1347 toExpand
A History of Epidemics in Britain
The historian is further confronted with the difficulty of identifying, under the confused nomenclature of by-gone days, the various pestilences described, and of assigning to them their proper place in modern nosology. Expand
