ROC and the bounds on tail probabilities via theorems of Dubins and F. Riesz

, 2009
For independent $X$ and $Y$ in the inequality $P(X\leq Y+\mu)$, we give sharp lower bounds for unimodal distributions having finite variance, and sharp upper bounds assuming symmetric densities bounded by a finite constant.
