make_disc_gamma: Make a discretized gamma distribution

In reconhub/simulacr: Outbreak simulation using branching processes

Description

This function is a simple wrapper around the packages epitrix and distcrete allowing to create a discretised Gamma distribution with given mean and standard deviration, returning a distcrete object.

Usage

make_disc_gamma(mean, sd)

Arguments

mean	the mean of the distribution
sd	the standard deviation of the distribution

Author(s)

Thibaut Jombart

Examples

serial_interval <- make_disc_gamma(15, 9)


## check PMF
plot(0:30, serial_interval$d(0:30), type = "h",
     lwd = 3, col = "navy",
     xlab = "Number of days", ylab = "probability",
     main = "Probability mass function")

## simulate random numbers
serial_interval$d(20)
