simulate_reproductivenumber1_ode: Basic SIR model

Description

A basic SIR model with 3 compartments and infection and recovery processes

Usage

simulate_reproductivenumber1_ode(S = 1000, I = 1, R = 0, b = 0.002,
  g = 1, tstart = 0, tfinal = 100, dt = 0.1)

Arguments

S

: starting value for Susceptible : numeric

I

: starting value for Infected : numeric

R

: starting value for Recovered : numeric

b

: infection rate : numeric

g

: recovery rate : numeric

tstart

: Start time of simulation : numeric

tfinal

: Final time of simulation : numeric

dt

: Time step : numeric

Value

The function returns the output as a list. The time-series from the simulation is returned as a dataframe saved as list element ts. The ts dataframe has one column per compartment/variable. The first column is time.

Warning

This function does not perform any error checking. So if you try to do something nonsensical (e.g. have negative values for parameters), the code will likely abort with an error message.

Details

The model includes susceptible, infected, and recovered compartments. The two processes that are modeled are infection and recovery. The simulation also monitors the number of infected and when they drop below 1, they are set to 0.

Examples

# NOT RUN {
 
# To run the simulation with default parameters:  
result <- simulate_reproductivenumber1_ode() 
# }
