enzymes: Liver Enzyme Data

In pmlr: Penalized Multinomial Logistic Regression

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).
