Description

The Oxboys data frame has 234 rows and 4 columns.

Arguments

Format

This data frame contains the following columns:
Subject
an ordered factor giving a unique identifier for each boy in the experiment
age
a numeric vector giving the standardized age (dimensionless)
height
a numeric vector giving the height of the boy (cm)
Occasion
an ordered factor - the result of converting age from a continuous variable to a count so these slightly unbalanced data can be analyzed as balanced.

Details

These data are described in Goldstein (1987) as data on the height of a selection of boys from Oxford, England versus a standardized age.
