 #' @description
 #' `intvn_reduce_mean()` is a helper for the \code{simulate_*()} functions. It
-#' modifies the relevant arguments of the offspring distribution in order to
-#' mimic the impact of an intervention. In particular, it scales the mean of
-#' the offspring distribution. Currently, it can only handle the poisson and
-#' negative binomial distributions and errors when other offspring
-#' distributions are specified alongside `intvn_scale_r0`.
