Description Usage Arguments Value Examples

Party nationalization score is a measure for the uniformity of vote share of a party over subnational units (provinces for Ecuador). It is computed as 1 minus Gini inequality index (Jones and Mainwaring, 2003)

*PNS = 1 - G*

*G = (2*sum(i*xi)) / (n*sum(xi)) - (n + 1)/n*

in which G is the Gini inequality index, xi is the vote share in the province ith, indexed in non-decreasing order (xi <= xi+1) i is an index from 1 to n n is the total of provinces

Party nationalization score is a number from 0 to 1, a low value (near 0) means a low level of nationalization, i.e. heterogeneous distribution of vote shares in subnational territorial units.

High score (near 1) indicates a high level of nationalization, i.e. homogeneous distribution of vote shares in subnational territorial units.
