The algebra and geometry of β

Abstract

Some operations relating to signal detection theory (SDT) analysis are facilitated by expressing β as a function of the z-transformed hit and false alarm rates, z1 and z0, respectively. This expression for the simplest equal-variance SDT model is β = exp[1/2(zo + z1)(zo − z1)]. © 1981, The psychonomic soceity, inc. All rights reserved.
