I arrived at a very similar solution to Mikko Marttila's, though I still think there's no need to fixate so much on the BCa interval. I ran a simulation on the standard bivariate normal with correlation 0.5, for which the Spearman rank correlation is also known, and d...
Spearman rank correlation between content interestingness and the topical diversity of user interests as a function of how many followers users have.Lilian WengFilippo Menczer
while the Kendall rank correlation and Spearman correlation capture how one variable consistently increases or decreases with the other, even if the relationship isn't perfectly linear. The Point-Biserial correlation is used when one variable is continuous and the other is binary. These different meth...
R(x)andR(y)denotes the rank of the x and y variables. R(x)andR(y)are the mean ranks. The Pearson coefficient and theSpearman correlationare pretty close. If there is an outlier, you may need to use theSpearman correlation. Use of Spearman correlation: ...

(2004), social support can take many forms, including but not limited to instrumental support (e.g., helping to solve a problem), tangible support (e.g., providing goods and services), informational support (e.g., providing advice), and emotional support (e.g., giving reassurance). ...
Equation 5 show the R-Score metric, where r(i, j) is the rating of the item i in the rank, d is a median rating and represents a half-life decay value. Besides this R-score, there are other ranking scores metrics, such as Kendall and Spearman rank correlation and Normalized ...
Spearman rank-order correlation. Spearman’s correlation coefficient (rs) measures the direction (+/−) as well as the strength of the monotonic association of two variables with non-parametric distribution [12]. Four degrees of correlation were defined: important (0.80–1.00), moderate (0.50–...
