The first column contains the probabilities <code>alpha</code> and the second column contains the estimated quantiles of the distribution at those probabilities derived from the spline. </p> </dd> <dt>points</dt><dd> <p>A matrix of evaluations of the saddlepoint approximation. The first column contains the values of <code>t</code> which were used, the second and third contain the density and cdf approximations at those points and the rest of the columns contain the solutions to the saddlepoint equations. When <code>type</code> is <code>"simp"</code>, there is only one of those. When <code>type</code> is <code>"cond"</code> there are <code>2*d-1</code> where <code>d</code> is the number of columns in <code>A</code> or the output of <code>A(t,...{})</code>. The first <code>d</code> of these correspond to the numerator and the remainder correspond to the denominator. </p> </dd> <dt>distn</dt><dd> <p>An object of class <code>smooth.spline</code>. This corresponds to the spline fitted to the saddlepoint cdf approximations in points in order to approximate the entire distribution. For the structure of the object see <code>smooth.spline</code>. </p> </dd> <dt>call</dt><dd> <p>The original call to <code>saddle.distn</code> which generated the object. </p> </dd> <dt>LR</dt><dd> <p>A logical variable indicating whether the Lugananni-Rice approximations were used. </p> </dd> </dl> <h3>See Also</h3> <p><code><a href="lines.saddle.distn.html">lines.saddle.distn</a></code>, <code><a href="saddle.distn.html">saddle.distn</a></code>, <code><a href="print.saddle.distn.html">print.saddle.distn</a></code> </p> <hr /><div style="text-align: center;">[Package <em>boot</em> version 1.3-22 <a href="00Index.html">Index</a>]</div> </body></html>
