fretsheads: Frets' Heads

In SIN: A SINful Approach to Selection of Gaussian Graphical Markov Models

Description

Head measurements on the first an the second adult son in a sample of 25 families. The 4 variables are:

• head length (first son),

• head breadth (first son),

• head length (second son),

• head breadth (second son).

Usage

data(fretsheads)

Format

A list providing a summary of the data. The list contains:

fretsheads$means	:	the mean vector,
fretsheads$stddev	:	the vector of standard deviations,
fretsheads$corr	:	the correlation matrix, and
fretsheads$n	:	the sample size.
