enzymes: Liver Enzyme Data

Description

Liver enzyme data collected from 218 patients with liver disease (Plomteux, 1980). The laboratory profile consists of enzymatic activity measured for four liver enzymes: aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutamate dehydrogenase (GLDH) and ornithine carbamyltransferase (OCT).

Format

A data frame with 218 rows and the following 6 columns:

  • Patient: Patient ID
