Beta_mat_form: Generate an infection rate matrix.

In BenjamenSimon/EpidemicR: Stochastic modelling and inference for epidemics.

Description

This function generates a beta matrix given a distance function, values of beta, and the distances at which the infection rate changes. It works for a heterogeneous population with a near vs. far spatial kernel.

Usage

Beta_mat_form(dist.mat, betas, ds)

Arguments

dist.mat	An NxN matrix of the pairwise distances between individuals.
betas	A descending vector of at least length 2 of the different infection rates at each level.
ds	An acsending vector of length length(betas)-1 which contains the distances at which the infection rate changes.

Value

The function returns an NxN matrix of the pairwise infection rates between individuals.

Examples

distance_mat <- Dist_mat_unif(N=100, xlim = 20, ylim = 20)[[2]]
Beta_mat_form(distance_mat, c(0.004, 0.002), 10)
