These new coefficients, the signed Klotz and the signed Mood, generalize the correspondent rank-order coefficients to measure the agreement between two sets of ranks previously proposed by the authors [1]. Under the null hypothesis of no agreement or no association among the rankings, the asymptotic distribution of these new coefficients was derived. To illustrate the worth of these measures, an example is presented to compare them with the Kendall’s coefficient and the van der Waerden correlation coefficient.engRank-order correlationWeighted coefficients ·Concordance measuresSigned Klotz coefficient ·Signed Mood coeficientevan der Waerden coefficientconference objecthttps://doi.org/10.1007/978-3-030-24296-1_3
