Title:  Estimate Asymptomatic Cases via Capture/Recapture Methods 

Description:  Estimate the lower and upper bound of asymptomatic cases in an epidemic using the capture/recapture methods from Böhning et al. (2020) <doi:10.1016/j.ijid.2020.06.009> and Rocchetti et al. (2020) <doi:10.1101/2020.07.14.20153445>. Note there is currently some discussion about the validity of the methods implemented in this package. You should read carefully the original articles, alongside this answer from Li et al. (2022) <doi:10.48550/arXiv.2209.11334> before using this package in your project.

Estimate the proportion of asymptomatic cases by capture/recapture
estimate_asympto(date, cases, deaths, bounds = c("lower", "upper"))
estimate_asympto(date, cases, deaths, bounds = c("lower", "upper"))
date 
A vector containing the dates 
cases 
A numeric vector containing the number of new cases at each

deaths 
A numeric vector containing the number of new deaths at each

bounds 

A data.frame
with two or three columns (depending on the value of
the bounds
argument):
date
: the original date
column
lower
: the lower bound of asymptomatic cases
upper
: the upper bound of asymptomatic cases
