Let $X$ and $Y$ be two continuous random variables with common support and with PDF $f(x)$ and $g(y)$. For any $0 \leq \alpha \leq 1$, and any constant $\beta$ within the support of $X$ and $Y$ such that $\Pr [Y>\beta ] >0$ and that $\Pr[Y\leq \beta ] > 0$,   we define
\begin{equation}
D_{\alpha,\beta}(f \| g) = 1 - \alpha \Pr[X \leq \beta \mid Y>\beta ] - ( 1- \alpha) \Pr[X > \beta \mid Y\leq\beta ] \:, 
\tag{1}\end{equation}
as a measure of distance of $f$ from $g$ at point $\beta$. Two questions: 

1) Is $D_{\alpha,\beta}(f \| g)$ a divergence of distribution $f$ from $g$ at point $\beta$?  

2) Is there any relationship between (1) and the well-known distance (or divergence) measures? 

Special case of $\alpha = \Pr[Y>\beta]$ is important. Moreover, for notational simplicity, I did not mention that $D_{\alpha,\beta}(f \| g)$ also depends on the joint distribution of $X$ and $Y$.
