Matched Receiver Operating Characteristic (roc) Analysis and Propensity Scores
نویسنده
چکیده
1. Introduction Many diagnostic tests are quantitative especially in clinical chemistry. Receiver operating characteristic (ROC) analysis is well recognized statistical tool for the evaluation how well the diagnostic test can discriminate diseased and non-diseased populations. The area under ROC curve (AUC) is often used to summarize the diagnostic accuracy of the diagnostic test. This area, a measure of performance of a test, is equal to P(X<Y).

متن کاملNonparametric Analysis of Fingerprint Data
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint similarity scores. In this paper, we present an analysis of the discrete distribution functions of the match and non-match similarity scores...
