rad.model: Radiation model

In obrady/SpatialDengue: Fits and simulates a spatial model of the vector-borne disease dengue

Description

Human movement model based on radiation, for details see Simini et al. (2012) Nature. 484, 96-100

Usage

rad.model(m, n, s)

Arguments

m	human population size in patch m (home patch)
n	human population size in patch n
s	human population size in all pixels within the radius m -> n, excluding m and n

Details

returns the predicted flux between pixels m and n

Examples

popmat <- matrix(round(runif(16, 5, 20), 0), nrow = 4, ncol = 4)
m <- popmat[1, 1]
n <- popmat[3, 2]
distm <- as.matrix(dist(popmat)) # creates a distance matrix
r <- distm[3, 2]
s <- sum(popmat[distm <= r]) - m - n
rad.model(m, n, s)
