# Gilby: Clothing and Intelligence Rating of Children In vcdExtra: 'vcd' Extensions and Additions

## Description

Schoolboys were classified according to their clothing and to their teachers rating of "dullness" (lack of intelligence), in a 5 x 7 table originally from Gilby (1911). Anscombe (1981) presents a slightly collapsed 4 x 6 table, used here, where the last two categories of clothing were pooled as were the first two categories of dullness due to small counts.

Both `Dullnes` and `Clothing` are ordered categories, so models and methods that examine their association in terms of ordinal categories are profitable.

## Usage

 `1` ```data(Gilby) ```

## Format

A 2-dimensional array resulting from cross-tabulating 2 variables for 1725 observations. The variable names and their levels are:

 No Name Levels 1 `Dullness` `"Ment. defective", "Slow", "Slow Intell", "Fairly Intell", "Capable", "V.Able"` 2 `Clothing` `"V.Well clad", "Well clad", "Passable", "Insufficient"`
