serial interval refers to a range of likely values from this distribution,
although it is typically reported as the mean.

`serial` to `TRUE` causes this discretized distribution to be returned in
addition to the estimate of R0. Furthermore, the method can be used whether or
not the serial interval (specified as the parameter `mu`) is known. When `mu` is
