## General Health Questionnaire

### Description

Data from an psychiatric screening questionnaire

### Usage

    data("GHQ")

### Format

A data frame with 22 observations on the following 4 variables.

`GHQ`
  the General Health Questionnaire score.
`sex`
  a factor with levels `female` and `male`
`cases`
  the number of diseased subjects.
`non.cases`
  the number of healthy subjects.

### Details

The data arise from a study of a psychiatric screening questionnaire called the GHQ (General Health Questionnaire, see Goldberg, 1972). Here the main question of interest is to see how caseness is related to gender and GHQ score.
