elastase: Leukocyte Elastase dataset

In GsymPoint: Estimation of the Generalized Symmetry Point, an Optimal Cutpoint in Continuous Diagnostic Tests

Description

The elastase 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).

Usage

Format

elas

leukocyte elastase. Numerical vector

status

true disease status (absence/presence of coronary artery disease). Numerical vector (0=absence, 1=presence)
