Schizophrenia Data

Description

Though disorder and early onset of schizophrenia.

Usage

data("schizophrenia2")

Format

A data frame with 220 observations on the following 4 variables.

subject

the patient ID, a factor with levels 1 to 44.

onset

the time of onset of the disease, a factor with levels < 20 yrs and > 20 yrs.

disorder

whether thought disorder was absent or present, the response variable.

month

month after hospitalisation.

Details

The data were collected in a follow-up study of women patients with schizophrenia. The binary response recorded at 0, 2, 6, 8 and 10 months after hospitalisation was thought disorder (absent or present). The single covariate is the factor indicating whether a patient had suffered early or late onset of her condition (age of onset less than 20 years or age of onset 20 years or above). The question of interest is whether the course of the illness differs between patients with early and late onset?
