Its value is between <i>1/k</i> and 1. </p> <p>The normalized form of the coefficient is also given. It is defined as <i>(F(k) - 1/k) / (1 - 1/k)</i>, and ranges between 0 and 1. A low value of Dunn's coefficient indicates a very fuzzy clustering, whereas a value close to 1 indicates a near-crisp clustering. </p> </td></tr> <tr valign="top"><td><code>clustering</code></td> <td> <p>the clustering vector of the nearest crisp clustering, see <code><a href="partition.object.html">partition.object</a></code>.</p> </td></tr> <tr valign="top"><td><code>k.crisp</code></td> <td> <p>integer (<i><= k</i>) giving the number of <em>crisp</em> clusters; can be less than <i>k</i>, where it's recommended to decrease <code>memb.exp</code>.</p> </td></tr> <tr valign="top"><td><code>objective</code></td> <td> <p>named vector containing the minimal value of the objective function reached by the FANNY algorithm and the relative convergence tolerance <code>tol</code> used. </p> </td></tr> <tr valign="top"><td><code>convergence</code></td> <td> <p>named vector with <code>iterations</code>, the number of iterations needed and <code>converged</code> indicating if the algorithm converged (in <code>maxit</code> iterations within convergence tolerance <code>tol</code>). </p> </td></tr> <tr valign="top"><td><code>diss</code></td> <td> <p>an object of class <code>"dissimilarity"</code>, see <code><a href="partition.object.html">partition.object</a></code>.</p> </td></tr> <tr valign="top"><td><code>call</code></td> <td> <p>generating call, see <code><a href="partition.object.html">partition.object</a></code>.</p> </td></tr> <tr valign="top"><td><code>silinfo</code></td> <td> <p>list with silhouette information of the nearest crisp clustering, see <code><a href="partition.object.html">partition.object</a></code>.</p> </td></tr> <tr valign="top"><td><code>data</code></td> <td> <p>matrix, possibibly standardized, or NULL, see <code><a href="partition.object.html">partition.object</a></code>.</p> </td></tr> </table> <h3>GENERATION</h3> <p>These objects are returned from <code><a href="fanny.html">fanny</a></code>. </p> <h3>METHODS</h3> <p>The <code>"fanny"</code> class has methods for the following generic functions: <code>print</code>, <code>summary</code>. </p> <h3>INHERITANCE</h3> <p>The class <code>"fanny"</code> inherits from <code>"partition"</code>. Therefore, the generic functions <code>plot</code> and <code>clusplot</code> can be used on a <code>fanny</code> object. </p> <h3>See Also</h3> <p><code><a href="fanny.html">fanny</a></code>, <code><a href="print.fanny.html">print.fanny</a></code>, <code><a href="dissimilarity.object.html">dissimilarity.object</a></code>, <code><a href="partition.object.html">partition.object</a></code>, <code><a href="plot.partition.html">plot.partition</a></code>. </p> <hr /><div style="text-align: center;">[Package <em>cluster</em> version 2.0.8 <a href="00Index.html">Index</a>]</div> </body></html>
