“…It is clear that if the random quantities and , associated with and , are non-negative, then and are equal to and , respectively. It should be mentioned at this point that Asadi et al [2] defined, in Subsection 3.2, a Kullback–Leibler type divergence function between two non-negative functions and which provides a unified representation of the measures (6), (23) and (24), with , being probability density function, cumulative distribution function and survival function, respectively. Based on Asadi et al [7], for non-negative random variables and , associated with and , respectively, and (23), (24) are simplified as follows, and …”
