From: A threshold-free approach with age-dependency for estimating malaria seroprevalence
Mixture distributions of PfAMA1 and PfMSP\(1_{19}\) antibodies for individuals between ages 1 and 16 using M1. These mixture distributions are derived from Eq. (1), and all the data of individuals aged 1–16 are analysed together. The red dotted lines illustrate the seropositivity thresholds (\(\mu _{S^-} + 3 \sigma _{S^-}\)), above which individuals are be classified as \(S^+\) in traditional analysis
