Ability of AR to detect signals with different Min_lifts.

*Youden’s index = (sensitivity + specificity) - 1: the power of finding true positive and true negative signals.Abbreviations: Min_lift: minimum lift.*Youden指数（Youden’s index）=（灵敏度（sensitivity）+特异度（specificity））-1：该指标用于识别真阳性（true positive）与真阴性（true negative）信号的效能。缩写说明：Min_lift 指代最小提升度（minimum lift）。
