In alanarnholt/PASWR2: Probability and Statistics with R, Second Edition

Dopamine Activity

Description

Twenty-five patients with schizophrenia were classified as psychotic or nonpsychotic after being treated with an antipsychotic drug. Samples of cerebral fluid were taken from each patient and assayed for dopamine β-hydroxylase (DBH) activity. The dopamine measurements for the two groups are in nmol/ml-hour per milligram of protein.

Usage

SCHIZO
