چکیده
|
In this note we correct an error on the possible maximum difference between the (measure of dependence)schweizer and wolff’s σ and the absolute value of the (measure of concordance) spearman’s ρ given in [8]. moreover,we provide a possible value for that possible, leaving its proof as an open problem.
