Susceptible Exposed Infected Removed model (SEIR connected)

Source: R/ModelSEIRCONN.R
ModelSEIRCONN.Rd

The SEIR connected model implements a model where all agents are connected. This is equivalent to a compartmental model (wiki).

Usage

ModelSEIRCONN(
  name,
  n,
  prevalence,
  contact_rate,
  transmission_rate,
  incubation_days,
  recovery_rate
)

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

Arguments

name

String. Name of the virus.

n

Number of individuals in the population.

prevalence

Initial proportion of individuals with the virus.

contact_rate

Numeric scalar. Average number of contacts per step.

transmission_rate

Numeric scalar between 0 and 1. Probability of transmission.

incubation_days

Numeric scalar greater than 0. Average number of incubation days.

recovery_rate

Numeric scalar between 0 and 1. Probability of recovery_rate.

x

Object of class SEIRCONN.

main

Title of the plot.

...

Currently ignore.

Value

The plot function returns a plot of the SEIRCONN model of class epiworld_model.
