The authors investigate the difference of two correlated VUS (Volume Under a Surface) to compare two treatments for discrimination of three-class classification data. A jackknife empirical likelihood (JEL) procedure is used. They showed that that the empirical log-likelihood ratio has a limiting chi-square distribution. Through numerical studies, they observed that the JEL confidence intervals outperform those based on the normal approximation method. The method proposed is applied to a real data set of the diagnosis for early-stage Alzheimer's disease.
