university1993

Data from a study by the <em>U.S. News and World Report</em> magazine with
the purpose of college ranking. Druzdzel and Glymour choose 8 variables
and after removing some universities give a correlation matrix for 159
universities. The 8 variables are:
  [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

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.
