EpiILM (version 1.2)

epiBR0:

Description

Calculates the basic reproduction number for the specified SIR model and data set

Usage

epiBR0(x=NULL, y=NULL, contact=NULL, alpha, beta, spark=NULL, infperiod, 

Sformula=NULL, tmax, niter)

Arguments

x
X coordinates of individuals
y
Y coordinates of individuals
contact
Contact network(s)
alpha
Susceptibility parameter(>0)
beta
Spatial parameter(s) (>0) or network parameter (s) (>0) if contact is used
spark
Sparks parameter (>=0), representing infections unexplained by other parts of the model or infections coming in from outside the observed population, default value is zero
infperiod
Length of infectious period for each individual
Sformula
An object of class formula. See formula

Individual-level covariate information passable through this argument. An expression of the form ~ model is interpreted as a specification that the susceptibility function, \(\Omega_s(i) \) is modelled by a linear predictor specified symbolically by the model term. Such a model consists of a series of terms separated by + and - operators. If there is no covariate information, Sformula is null.

tmax
The last time point of simulation
niter
Number of epidemic simulations to calculate basic reproduction number

Value

BasicR0
The basic reproduction number value
simulated_BR0
Number of infections per simulation
