The Migration-weighted Out-migration Gini Index is a weighted version of the Out-migration Field Gini Index (migration.gini.out) "according to the zone of destination's share of total migration and the mean of the weighted values is computed as":
MWG^O = \frac{ ∑_i G^O_i \frac{∑_j M_{ij}}{∑_{ij} M_{ij}}}{n}
