Accommodating covariates in receiver operating characteristic analysis Melbourne sex webcams

Furthermore, the FIC improves the accuracy of the estimated AUC compared with other criteria.In medical studies, the receiver operating characteristic (ROC) curve is a tool of extensive use to analyze the discrimination capability of a diagnostic variable. (eds) Computational Science and Its Applications -- ICCSA 2015.

Incorporating covariates in the analysis can potentially enhance information gathered from the biomarker, as its discriminatory ability may depend on these.

In this paper we propose a dependent Bayesian nonparametric model for conditional ROC estimation.

Oftentimes, factors other than disease affect marker observations.

For example, levels of prostate-specific antigen (PSA), a biomarker widely used to screen men for prostate cancer, tend to increase with age.

Individuals who are disease-free earlier may develop the disease later due to longer study follow-up, and also their marker value may change from baseline during follow-up.
