elastase

The <code>elastase</code> dataset was obtained from a study carried out in the Cardiology Department at the Galicia General Hospital (Santiago de Compostela, Spain). This study (Amaro et al., 1995) was conducted to assess the clinical usefulness of leukocyte elastase determination in the diagnosis of coronary artery disease (CAD).

datasets

Estimation of the cutpoint defined by the Generalized Symmetry point in a binary classification setting based on a continuous diagnostic test or marker. Two methods have been implemented to construct confidence intervals for this optimal cutpoint, one based on the Generalized Pivotal Quantity and the other based on Empirical Likelihood. Numerical and graphical outputs for these two methods are easily obtained.
