Abstract
Each of b judges independently rank kh out of t objects, h = 1, 2, ... , b. This basic design is replicated n times, resulting in nb independent blocks. The methods introduced in Alvo and Cabilio (1991) to test for concordance among the judges in a BIBD are extended to this situation and applied to a statistic based on Kendall's tau. This statistic is then analyzed for a situation not considered in Alvo and Cabilio (1991), and it is shown to maintain its superior efficiency over the Durbin test.Incomplete blocks Balanced Doubly balanced Ranking Spearman correlation Kendall correlation Asymptotic distributions Bahadur efficiency
