Predictive Value Generalization Bounds [PDF]
arXiv, 2020 In this paper, we study a bi-criterion framework for assessing scoring functions in the context of binary classification. The positive and negative predictive values (ppv and npv, respectively) are conditional probabilities of the true label matching a classifier's predicted label.

Transforming response values in small area prediction [PDF]
arXiv, 2015 In real applications of small area estimation, one often encounters data with positive response values. The use of a parametric transformation for positive response values in the Fay-Herriot model is proposed for such a case. An asymptotically unbiased small area predictor is derived and a second-order unbiased estimator of the mean squared error is ...

Interpretation of a diagnostic test in statistical terms
Current Medicine Research and Practice, 2012 In medical practice, various tests are used for confirmation or diagnosis of a disease. For clinical implications, these tests are compared with the definitive test which is the gold standard and their diagnostic utility is expressed by various ...

Frontiers in Neurology, 2016 Objectives: The primary aim was to determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the bedside head impulse test (bHIT) using the video HIT (vHIT) as the gold standard for quantifying the ...

Cytometry Part B: Clinical Cytometry, 2019 AbstractBackgroundThe role of CD200 in the differential diagnosis of chronic lymphocytic leukemia (CLL) and classical mantle cell lymphoma (MCL) is well established. Its role in the differential diagnosis of CLL and other lymphoproliferative disorders (LPD) is less clear, in particular its positive predictive value (PPV).Materials and methodsWe ...

Comparison of predictive values with paired samples [PDF]
arXivPositive predictive value and negative predictive value are two widely used parameters to assess the clinical usefulness of a medical diagnostic test. When there are two diagnostic tests, it is recommendable to make a comparative assessment of the values of these two parameters after applying the two tests to the same subjects (paired samples).
