If the returns of the two assets are normally distributed, their rank correlation and Pearson’s correlation would not be equal. 解释: C is correct. Correlation and the slope of the regression are intimately related, as regression explains the sense in which correlation measures linear dependence...
Within the bounds of a general theory of rank correlation two particular measures have been adopted widely: Spearman's rank correlation coefficient, , in which ranks replace variates in Pearson's product-moment correlation calculation; and Kendall's , in which the disarray of x-ordered data due ...

Rank correlation coefficientsRepeated measuresConsideration is given to longitudinal data settings in which an ordinal response variable is observed at two or more visits for each subject in two or more ordered groups with at least moderately large sample sizes (e.g., overall n ⥠40)....
A rank correlation coefficientmeasures the degree of similarity between two rankings, and can be used to assess the significance of the relation between them. For example, two common nonparametric methods of significance that use rank correlation are the Mann–Whitney U test and the Wilcoxon signed...
Rank correlation is used quite extensively in school subjects other than mathematics,particularly geography and biology. There are two accepted measures of rank correlation, Spearman’s and Kendall’s; of these, Spearman’s is the more widely used. This paper is written to give teachers of ...
