Course Goal / Objective
With this course, it is aimed that the student will be able to model ROC curves, which are frequently used as accuracy measure, to analyze correlated ROC data with proper approaches, and to understand and apply correction methods for biases that occur in accuracy measure evaluation studies.
Course Content
In this course, regression analysis for ROC curve used as an accuracy measure, analysis of correlated ROC data, biases in accuracy measure evaluations and their correction will be discussed.
