Abstrakt: When Lorenz curves cross, conditional coefficient of variation curve can be used to test the inequality dominance. In the present paper, confidence bands are provided for conditional coefficient of variation curve. Based on these confidence bands a multiple comparison test is proposed for testing the dominance of conditional coefficient of variation curve. The power of the test is computed and a real life illustration is given at the end. [ABSTRACT FROM AUTHOR]
