#' This method is based on an approximation of the SIR model, which is most valid at the beginning of an epidemic.\r
#' The method assumes that the mean of the serial distribution (sometimes called the serial interval) is known.\r
#' The final estimate can be quite sensitive to this value, so sensitivity testing is strongly recommended.\r
