SROC curves from the five choices of BREM approach (red = R&G, blue = D-on-S, green = Major axis, cyan = η -on- ξ and gray = ξ -on- η ) and MREM approach (black) for the CAGE data set. The curves for the primary and non-primary carry population are given in the same color but with solid and broken lines respectively. The three approaches (R&G, D on S and Major axis) give the same estimates (overlapped curves).
