Improving estimation of the volume under the ROC surface when data are missing not at random
Duc-Khanh To, Gianfranco Adimari, Monica Chiogna
In this paper, we propose a mean score equation-based approach to estimate the the volume under the receiving operating characteristic (ROC) surface (VUS) of a diagnostic test, und…

Structure learning of undirected graphical models for count data
Thi Kim Hue Nguyen, Monica Chiogna
Biological processes underlying the basic functions of a cell involve complex interactions between genes. From a technical point of view, these interactions can be represented thro…

Nonparametric Estimation of ROC Surfaces Under Verification Bias
Khanh To Duc, Monica Chiogna, Gianfranco Adimari
Verification bias is a well known problem when the predictive ability of a diagnostic test has to be evaluated. In this paper, we discuss how to assess the accuracy of continuous-s…
