Spatial Gini Indexes

Description

This is a wrapper function computing all the following Gini indices:

• Total Flows Gini Index (migration.gini.total)

• Rows Gini Index (migration.gini.row)

• Standardized Rows Gini Index (migration.gini.row.standardized)

• Columns Gini Index (migration.gini.col)

• Standardized Columns Gini Index (migration.gini.col.standardized)

• Exchange Gini Index (migration.gini.exchange)

• Standardized Exchange Gini Index (migration.gini.exchange.standardized)

• Out-migration Field Gini Index (migration.gini.out)

• Migration-weighted Out-migration Gini Index (migration.weighted.gini.out)

• In-migration Field Gini Index (migration.gini.in)

• Migration-weighted In-migration Gini Index (migration.weighted.gini.in)

• Migration-weighted Mean Gini Index (migration.weighted.gini.mean)

Usage

migration.gini(m, corrected = TRUE)

Arguments

m	migration matrix
corrected	to use Bell et al. (2002) updated formulas instead of Plane and Mulligan (1997)

Value
