WebJan 23, 2024 · An AFROC curve is a plane curve whose area under the curve (AUC) indicates an observer performance ability. In the following, Φ() denotes the cumulative distribution function on the standard Gaussian disribution. The so-called AFROC curve is defined by (ξ(t),η(t) ) =(1-e^{-t}, Φ( bΦ^{-1}(\\exp(-t) )- a ) )for all t >0 and some fixed real …
