saddle.distn.object {boot} | R Documentation |
Class of objects that result from calculating saddlepoint distribution
approximations by a call to saddle.distn
.
This class of objects is returned from calls to the function saddle.distn
.
The class "saddle.distn"
has methods for the functions lines
and
print
.
Objects of class "saddle.distn"
are implemented as a list with the following
components.
alpha
and the second column contains the estimated quantiles of the distribution at
those probabilities derived from the spline.
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. When type
is "simp"
, there is only one of those. When type
is "cond"
there
are 2*d-1
where d
is the number of columns in A
or the output of
A(t,...{})
. The first d
of these correspond to the numerator and the
remainder correspond to the denominator.
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 see smooth.spline
.
saddle.distn
which generated the object.
