Age effect on prion infection prevalence.
(a) Age distribution of animals sampled by year. (b) Derived posterior probability density for prevalence (P(z = 1)) across observed ages. Black dots represent mean values and gray dots, 95% confidence intervals. Left y-axis shows prevalence within age groups demonstrating the predominant age of infected animals lies between 2 and 10 years as previously documented. The right y-axis and the histogram in the background show the observed frequency of ages of elk sampled in this study.
