tsirSim: Function to simulate the stochastic TSIR

In epimdr2: Functions and Data for "Epidemics: Models and Data in R (2nd Edition)"

Function to simulate the stochastic TSIR

Description

Function to simulate the stochastic TSIR assuming stochasticity in transmission and a Poisson birth-death process

Usage

tsirSim(
  alpha = 0.97,
  B = 2300,
  beta = 25,
  sdbeta = 0,
  S0 = 0.06,
  I0 = 180,
  IT = 520,
  N = 3300000
)

Arguments

alpha	the exponent on I
B	the birth rate
beta	the transmission rate
sdbeta	the standard deviation on beta
S0	the initial susceptible fraction
I0	the initial number of infected
IT	the length of simulation
N	the population size

Value

A list with time series of simulated infected and susceptible hosts

Examples

out = tsirSim()
