Description Usage Arguments Value Author(s)

Given the populations of A and B and the distance between them, return the estimated population flow between them modeled as \phi(A,B) = K N_A^\alphaN_B^\beta/r_AB^\gamma..

`N_from`	population of the source
`N_to`	population of the destination
`pow_N_from`	power on the population of the source
`pow_N_to`	power on the population of the destination
`pow_dist`	power on the distance between the source and the destination
`dist`	distance between the two places
