Saddlepoint Distribution Approximation Objects
Description
Class of objects that result from calculating saddlepoint distribution
approximations by a call to saddle.distn
.
Generation
This class of objects is returned from calls to the function
saddle.distn
.
Methods
The class "saddle.distn"
has methods for the functions
lines
and print
.
Structure
Objects of class "saddle.distn"
are implemented as a list with
the following components.
 quantiles

A matrix with 2 columns. The first column contains the probabilities
alpha
and the second column contains the estimated quantiles of the distribution at those probabilities derived from the spline.  points

A matrix of evaluations of the saddlepoint approximation. The first column contains the values of
t
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. Whentype
is"simp"
, there is only one of those. Whentype
is"cond"
there are2*d1
whered
is the number of columns inA
or the output ofA(t,...{})
. The firstd
of these correspond to the numerator and the remainder correspond to the denominator.  distn

An object of class
smooth.spline
. 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 seesmooth.spline
.  call

The original call to
saddle.distn
which generated the object.  LR

A logical variable indicating whether the LugananniRice approximations were used.
