  • On Binormal Magnetic Curves with Harmonicity in Terms of Inextensible Flows in Space
    Differential Equations and Dynamical Systems, 2019
    Co-Authors: Talat Korpinar

    Abstract:

    In this article, we consider inextensible condition for Binormal magnetic particles in the space. We give some conditions for flows of Lorentz forces. Moreover, we obtain harmonicity conditions for some Lorentz forces. Finally, we investigate the inextensible condition for electric field with Lorentz equation.

  • resampling techniques in the analysis of non Binormal roc data
    Medical Decision Making, 1995
    Co-Authors: Douglas Mossman

    Abstract:

    The methods most commonly used for analyzing receiver operating characteristic (ROC) data incorporate “Binormal” assumptions about the latent frequency distributions of test results. Although these assumptions have proved robust to a wide variety of actual frequency distributions, some data sets do not “fit” the Binormal model. In such cases, resampling techniques such as the jackknife and the bootstrap provide versatile, distribution-indepen dent, and more appropriate methods for hypothesis testing. This article describes the ap plication of resampling techniques to ROC data for which the Binormal assumptions are not appropriate, and suggests that the bootstrap may be especially helpful in determining con fidence intervals from small data samples. The widespread availability of ever-faster com puters has made resampling methods increasingly accessible and convenient tools for data analysis. Key words: receiver operating characteristic; ROC; resampling; jackknife; bootstrap; diagnostic testing; diagnostic…

  • roc curves and the Binormal assumption
    Journal of Neuropsychiatry and Clinical Neurosciences, 1991
    Co-Authors: Eugene Somoza, Douglas Mossman

    Abstract:

    : Previous articles in this series have described how receiver operating characteristic (ROC) graphs provide comprehensive graphic representations of the diagnostic performance of non-binary tests and have explained how one constructs “trapezoidal” ROC graphs in which discrete cutoff points are plotted and connected with line segments. In this article, we describe a set of mathematical assumptions that permit the generation of a continuous, smooth ROC curve for a given diagnostic test. These assumptions permit us to characterize a test’s performance using a small number of parameters and also to explore properties of diagnostic tests. In this article, we describe a set of mathematical assumptions that can be used to link receiver operating characteristic (ROC) curves to the underlying distribution of values of the diagnostic variable being measured. We will illustrate these assumptions using a diagnostic test that distinguishes alcohol abusers from normal consumers of alcohol and abstainers.
