This is the repository for the coarseDataTools R package. We use this as a development space. The most recent, stable version of the package can be downloaded either from CRAN ( or from the most recent release version on github (

This package contains functions to analyze coarsely observed data. Specifically, it contains functions to (1) fit parametric accelerated failure time models to interval-censored survival time data, and (2) estimate the case-fatality ratio in scenarios with underreporting. This package's development was motivated by applications to infectious disease: in particular, problems with estimating the incubation period and the case fatality ratio of a given disease. Sample data files are included in the package.
