epidist: Estimate Epidemiological Delay Distributions with 'brms'

Understanding and accurately estimating epidemiological delay distributions is important for public health policy. These estimates influence epidemic situational awareness, control strategies, and resource allocation. This package provides methods to address the key challenges in estimating these distributions, including truncation, interval censoring, and dynamical biases, following Park et al. (2024) <doi:10.1101/2024.01.12.24301247> and Charniga et al. (2024) <doi:10.1371/journal.pcbi.1012520>. These issues are frequently overlooked, resulting in biased conclusions. Built on top of 'brms', it allows for flexible modelling including time-varying and spatial effects and partially pooled estimates of demographic characteristics.
