vector of weights |
k |
multiple of the median income |
Medeiros (2006) defined an average affluence gap. Weighted gap (with weights w_1,w_2,...,w_n) is given by:
R^{Me}= \frac{∑_{i=1}^n \max\{x_i-ρ_w,0\}w_i}{∑_{i=1}^nw_i},
where x_i is an income of individual i, n is the number of individuals, ρ_w is the richness line. Medeiros' index is not standarized and is an absolute measure of richness.
