Fig. 2From: Estimating the proportion of guilty suspects and posterior probability of guilt in lineups using signal-detection modelsThe signal detection model for lineups. Left: unequal-variance model. Right: equal-variance model. μg and σg are the mean and standard deviation of the guilty-suspect distribution. μf and σf are the mean and standard deviation of the filler distribution. c1, c2, c3 are the response criteria for the low-, medium- (med), and high-response confidence regions. ID and No ID are response regions in which an identification is or is not made, respectivelyBack to article page
