author keywords: ROC surface; Verification bias correction; Trinormal model; MAR assumption

TL;DR: A Bayesian approach for estimating the ROC surface is proposed based on continuous data under a semi-parametric trinormality assumption and is applied to evaluate the performance of CA125 and HE4 in the diagnosis of epithelial ovarian cancer (EOC) as a demonstration. (via Semantic Scholar)

TL;DR: A Bayesian nonparametric approach is adopted by directly modeling the underlying distributions of the three categories by Dirichlet process mixture priors and it is found that the proposed method generally outperforms other approaches. (via Semantic Scholar)
