RadiationMixing

RadiationMixing(scenario=None, params=None)

Radiation migration model where outbound migration flux from origin to destination is enhanced by destination population and absorbed by the density of nearer destinations.

Formula:

\[M_{i,j} = k \frac{p_i p_j}{\left(p_i + \sum_{k \in \Omega(i,j)} p_k\right)\left(p_i + p_j + \sum_{k \in \Omega(i,j)} p_k\right)}\]

Parameters:

• include_home (bool) – Whether to include home in the migration matrix

• k (float) – Scale parameter (avg trip probability)
