Summary
Understanding and accurately estimating epidemiological delay distributions is important for public health policy. These estimates directly influence epidemic situational awareness, control strategies, and resource allocation. In this package, we provide methods to address the key challenges in estimating these distributions, including truncation, interval censoring, and dynamical biases. Despite their importance, these issues are frequently overlooked, often resulting in biased conclusions.
Installation
Installing the package
You can use the remotes
package to install the development version from Github (warning! this version may contain breaking changes and/or bugs):
remotes::install_github(
file.path("epinowcast", "epidist"),
dependencies = TRUE
)
Installing CmdStan (optional)
By default epidist
uses the rstan
package for fitting models. If you wish to use the cmdstanr
package instead, you will need to install CmdStan, which also entails having a suitable C++ toolchain setup. We recommend using the cmdstanr
package to manage CmdStan. The Stan team provides instructions in the Getting started with cmdstanr
vignette, with other details and support at the package site, but the brief version is:
# if you have not yet installed `epidist`, or you installed it without
# `Suggests` dependencies
install.packages(
"cmdstanr",
repos = c("https://mc-stan.org/r-packages/", getOption("repos"))
)
# once `cmdstanr` is installed
cmdstanr::install_cmdstan()
Note: You can speed up CmdStan installation using the cores
argument. If you are installing a particular version of epidist
, you may also need to install a past version of CmdStan, which you can do with the version
argument.

Organisation Website
Our organisation website includes links to other resources, guest posts, and seminar schedule for both upcoming and past recordings.
Community Forum
Our community forum has areas for question and answer and considering new methods and tools, among others. If you are generally interested in real-time analysis of infectious disease, you may find this useful even if do not use epidist
.
