Dopamine Activity

Source: R/AgainStart.R

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 \(\beta\)-hydroxylase (DBH) activity. The dopamine measurements for the two groups are in nmol/ml-hour per milligram of protein.

SCHIZO

Format

A data frame with 25 observations on the following 2 variables:

  • dopamine (dopamine activity level)

  • classification (factor with levels psychotic and nonpsychotic)
