fowlbones


  Bone measurements are taken on 276 white leghorn fowl. The 6 variables
  are:  
  <ul>
<li> skull length,
    </li>
<li> skull breadth,
    </li>
<li> humerous (wings),
    </li>
<li> ulna (wings),
    </li>
<li> femur (legs),
    </li>
<li> tibia (legs).

</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.
