Statistical and receiver operating characteristic analysis
Analytical methods from signal detection theory were applied in an effort to quantify the ability of cochlear nucleus (CN) units to signal changes in intensity. Of particular interest was the relation between this ability and the different patterns of discharge that characterize auditory neurons. Single-unit responses to best-frequency (BF) tone bursts were recorded from neurons in the gerbil c...
متن کاملReceiver Operating Characteristic Analysis of Eyewitness Memory
A police lineup presents a real-world signal-detection problem because there are two possible states of the world (the suspect is either innocent or guilty), some degree of information about the true state of the world is available (the eyewitness has some degree of memory for the perpetrator), and a decision is made (identifying the suspect or not). A similar state of affairs applies to diagno...
متن کاملReceiver Operating Characteristic ( ROC ) Curves
Assessment of predictive accuracy is a critical aspect of evaluating and comparing models, algorithms or technologies that produce the predictions. In the field of medical diagnosis, receiver operating characteristic (ROC) curves have become the standard tool for this purpose and its use is becoming increasingly common in other fields such as finance, atmospheric science and machine learning. T...
متن کاملMatched Receiver Operating Characteristic (roc) Analysis and Propensity Scores
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 ...
متن کاملWavelet and receiver operating characteristic analysis of heart rate variability.
Multiresolution wavelet analysis has been used to study the heart rate variability in two classes of patients with different pathological conditions. The scale dependent measure of Thurner et al. was found to be statistically significant in discriminating patients suffering from hypercardiomyopathy from a control set of normal subjects. We have performed Receiver Operating Characteristc (ROC) a...
