For p&gt;n, the matrix of partial correlations can be estimated based on p least-squares regression fits. However, for p&lt;n, theses least-squares problems are ill-posed and need to be regularized. This package contains four different regularized regression techniques for the estimation of the partial correlations: lasso, adaptive lasso, ridge regression, and partial least squares. </p></html>nicole kraemer, juliane schaeferTue, 05 May 2009 16:49:47 -0000http://mloss.org/software/rss/comments/186http://mloss.org/software/view/186/regressiongraphical modelssparse learning<b>Comment by Kelly Brown on 2009-06-12 21:47</b>http://mloss.org/comments/cr/14/186/#c370<p>The best information i have found exactly here.
