fretsheads


Head measurements on the first an the second adult son in a sample of 25
families. The 4 variables are:
  <ul>
<li> head length (first son),
    </li>
<li> head breadth (first son),
    </li>
<li> head length (second son),
    </li>
<li> head breadth (second son).
  </li>
</ul><p></p><p></p>

datasets

This package provides routines to perform SIN model selection
as described in Drton & Perlman (2004, 2008).  The selected models are
represented in the format of the 'ggm' package, which allows in
particular parameter estimation in the selected model.
