-#' WP method background function WP_known
-#'
-#' This is a background/internal function called by \code{WP}. It computes the maximum
-#' likelihood estimator of R0 assuming that the serial distribution is known and finite discrete.
-#'
-#' @param NT Vector of case counts.
-#' @param p Discretized version of the serial distribution.
-#'
-#' @return The function returns the maximum likelihood estimator of R0.
