A <code>glsStruct</code> may contain <code>corStruct</code> and <code>varFunc</code> objects. <code>NULL</code> arguments are not included in the <code>glsStruct</code> list. </p> <h3>Usage</h3> <pre> glsStruct(corStruct, varStruct) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>corStruct</code></td> <td> <p>an optional <code>corStruct</code> object, representing a correlation structure. Default is <code>NULL</code>.</p> </td></tr> <tr valign="top"><td><code>varStruct</code></td> <td> <p>an optional <code>varFunc</code> object, representing a variance function structure. Default is <code>NULL</code>.</p> </td></tr> </table> <h3>Value</h3> <p>a list of model variance-covariance components determining the parameters to be estimated for the associated linear model. </p> <h3>Author(s)</h3> <p>José Pinheiro and Douglas Bates <a href="mailto:bates@stat.wisc.edu">bates@stat.wisc.edu</a></p> <h3>See Also</h3> <p><code><a href="corClasses.html">corClasses</a></code>, <code><a href="gls.html">gls</a></code>, <code><a href="residuals.glsStruct.html">residuals.glsStruct</a></code>, <code><a href="varFunc.html">varFunc</a></code> </p> <h3>Examples</h3> <pre> gls1 <- glsStruct(corAR1(), varPower()) </pre> <hr /><div style="text-align: center;">[Package <em>nlme</em> version 3.1-139 <a href="00Index.html">Index</a>]</div> </body></html>
