Prevalence threshold (ϕe) and the geometry of screening curves
The relationship between a screening tests’ positive predictive value, ρ, and its target prevalence, ϕ, is proportional—though not linear in all but a special case. In consequence, there is a point of local extrema of curvature defined only as a function of the sensitivity a and specificity b beyond...
