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}*
