• An increasing rank correlation coefficient implies increasing agreement between rankings.
• Different metrics will correspond to different rank correlations.
• Define Kendall tau rank correlation coefficient \ tau as
• See Spearman's rank correlation coefficient.
• The observation that many centralities share this familial relationships perhaps explains the high rank correlations between these indices.
• Pvrank is a very recent R package that computes rank correlations and their p-values with various options for tied ranks.
• Other important contributions at this time included Charles Spearman's rank correlation coefficient that was a useful extension of the Pearson correlation coefficient.
• Rank correlation coefficients, such as Spearman's rank correlation coefficient and association, rather than as alternative measure of the population correlation coefficient.
• Rank correlation coefficients, such as Spearman's rank correlation coefficient and association, rather than as alternative measure of the population correlation coefficient.
• Finally, the rank correlation is the difference between the two proportions ( . 60 minus . 40 ), hence r = . 20.
• In SELDM, these three treatment variables are modeled by using the trapezoidal distribution and the rank correlation with the associated highway-runoff variables.
• Among them are percent agreement, Pearson's correlation coefficient r, Spearman's rank correlation coefficient ?, and Lin's concordance correlation coefficient.
• An alternative name for the Spearman rank correlation is the  grade correlation; in this, the  rank of an observation is replaced by the  grade.
• The Euclidean distance between SIFT-Rank descriptors is invariant to arbitrary monotonic changes in histogram bin values, and is related to Spearman's rank correlation coefficient.
• *Spearman s rank correlation coefficient " rho " measures the agreement between two coders ranking of the same set of " N " objects.
• If both variables are ordinal, meaning they are ranked in a sequence as first, second, etc ., then a rank correlation coefficient can be computed.
