Title:
Nonparametric Statistical Inference for Receiver Operating
Characteristic Curves in Measurement Error Models
Abstract:
The subject of this talk is nonparametric statistical evaluation of a continuous diagnostic marker by means of receiver operating characteristic (ROC) curves. Our goal is to develop minimax optimal and adaptive nonparametric estimation techniques for estimating the ROC curve and some of its summary indexes. Indexes of interest are the ROC curve, the area under the curve (AUC), the Youden Index and the optimal classification threshold.
We are interested in an experimental setup where direct observations of the marker are not at hand. Although ROC curve and its summary indexes are widely used in biostatistics and engineering, the literature on their parametric estimation in measurement error models is sparse and in a nonparametric setups almost does not exist.
In this talk we will focus on estimation of the AUC in measurement error models which is closely related to deconvolution of distribution functions.
