Özet
In this paper, as an alternative to both the average Kendall τ and average Spearman's ρ, we propose a new statistic, τ*, to test the null hypothesis of complete randomness amongst the n judges each rank r objects independently. We define τ* based on Rao's ideas of the diversity coefficient of a population. Monte Carlo experiments we made show that the test based on the proposed statistic has better and desirable power properties relative to competing tests.
