I wonder if it is fair is to compare the gini coefficient of two discrete distributions with different number of elements. If not, how can I adjust the coefficients for a fair comparison.
In particular, I'm interested in the case when the sum of values in both distributions are equal. For example, minutes played by players of two teams in a basketball game if they have different number of players (10 players in one team, 12 players in the other team) but for both teams sums plays 48 minutes x 5.
Other example, different partitioning of some surface in different regions, how to compare inequality for different partitioning if they have different number of subareas.
