Non parametric ROC summary statistics

Receiver operating characteristic (ROC) curves are useful statistical tools for medical diagnostic testing. It has been proved its capability to assess diagnostic marker’s ability to distinguish between healthy and diseased subjects and to compare different diagnostic markers. In this paper we introduce non parametric ROC summary statistics to assess a ROC curve across the entire range of FPFs ...

Probabilistic analysis of global performances of diagnostic tests: interpreting the Lorenz curve-based summary measures.

Several indices based on the receiver operating characteristic curve (ROC curve) have previously been found to possess probabilistic interpretations. However, these interpretations are based on some unrealistic diagnostic scenarios. In this paper, the author presents a new approach using the Lorenz curve. The author found that the summary indices of the Lorenz curve, that is, the Pietra index a...

Statistical Evaluation of Diagnostic Tests - Part 2 [Pre-test and post-test probability and odds, Likelihood ratios, Receiver Operating Characteristic Curve, Youden's Index and Diagnostic test biases].

I t h e p r e v i o u s a r t i c l e o n t h e s t a t i s t i c a l e v a l u a t i o n of diagnostic tests –Part 1, we u n d e r s t o o d t h e m e a s u r e s o f sensitivity, specificity, positive and negative predictive values. The use of these metrices stems from the fact that no diagnostic test is ever perfect and every time we carry out a test, it will yield one of four possible outco...

Exploring sources of heterogeneity in systematic reviews of diagnostic tests.

It is indispensable for any meta-analysis that potential sources of heterogeneity are examined, before one considers pooling the results of primary studies into summary estimates with enhanced precision. In reviews of studies on the diagnostic accuracy of tests, variability beyond chance can be attributed to between-study differences in the selected cutpoint for positivity, in patient selection...

Statistical Evaluation of Continuous-Scale Diagnostic Tests with Missing Data

The receiver operating characteristic (ROC) curve methodology is the statistical methodology for assessment of the accuracy of diagnostics tests or bio-markers. Currently most widely used statistical methods for the inferences of ROC curves are complete-data based parametric, semi-parametric or nonparametric methods. However, these methods cannot be used in diagnostic applications with missing ...
