Analysis of Antibody Data Using Skew-normal and Skew-T Mixture Models

Analysis of Antibody Data Using Skew-normal and Skew-T Mixture Models

Gaussian mixture models, which assume a Normal distribution for each component, are popular in antibody (or serological) data analysis to help determining antibody-positive and antibody-negative individuals. In this work, we advocate using finite mixture models based on Skew-Normal and Skew-t distr...
