SIRD model

Usage

ModelSIRD(name, prevalence, transmission_rate, recovery_rate, death_rate)

# S3 method for class 'epiworld_sird'
plot(x, main = get_name(x), ...)

Arguments

name

String. Name of the virus

prevalence

Double. Initial proportion of individuals with the virus.

transmission_rate

Numeric scalar between 0 and 1. Virus's rate of infection.

recovery_rate

Numeric scalar between 0 and 1. Rate of recovery_rate from virus.

death_rate

Numeric scalar between 0 and 1. Rate of death from virus.

x

Object of class SIR.

main

Title of the plot

...

Additional arguments passed to graphics::plot.

Value

  • The plot function returns a plot of the SIRD model of class epiworld_model.

Details

The initial_states function allows the user to set the initial state of the model. The user must provide a vector of proportions indicating the following values: (1) proportion of non-infected agents already removed, and (2) proportion of non-ifected agents already deceased.

Examples

model_sird <- ModelSIRD(
  name              = "COVID-19",
  prevalence        = 0.01,
  transmission_rate = 0.9,
  recovery_rate     = 0.1,
  death_rate        = 0.01
)

# Adding a small world population
agents_smallworld(
  model_sird,
  n = 1000,
  k = 5,
  d = FALSE,
  p = .01
)
