Usage
AbscontDistribution(r = NULL, d = NULL, p = NULL, q = NULL,
                   gaps = NULL, param = NULL, img = new("Reals"),
                   .withSim = FALSE, .withArith = FALSE,
                    .lowerExact = FALSE, .logExact = FALSE,
                   withgaps = getdistrOption("withgaps"),
                   low1 = NULL, up1 = NULL, low = -Inf, up =Inf,
                   withStand = FALSE,
                   ngrid = getdistrOption("DefaultNrGridPoints"),
                   ep = getdistrOption("TruncQuantile"),
                   e = getdistrOption("RtoDPQ.e"),
                   Symmetry = NoSymmetry())
Arguments
r
slot r to be filled
d
slot d to be filled
p
slot p to be filled
q
slot q to be filled
gaps
slot gaps (of class "matrix" with two columns) to be filled (i.e. t(gaps) must be ordered if read as vector)
param
parameter (of class "OptionalParameter")
img
image range of the distribution (of class "rSpace")
low1
lower bound (to be the lower TruncQuantile-quantile of the distribution)
up1
upper bound (to be the upper TruncQuantile-quantile of the distribution)
low
lower bound (to be the 100-percent-quantile of the distribution)
up
upper bound (to be the 100-percent-quantile of the distribution)
withStand
logical: shall we standardize argument function d to integrate to 1 --- default is no resp. FALSE
ngrid
number of gridpoints
ep
tolerance epsilon
e
exponent to base 10 to be used for simulations
withgaps
logical; shall gaps be reconstructed empirically?
.withArith
normally not set by the user, but if determining the entries supp, prob distributional arithmetics was involved, you may set this to TRUE.
.withSim
normally not set by the user, but if determining the entries supp, prob simulations were involved, you may set this to TRUE.
.lowerExact
normally not set by the user: whether the lower.tail=FALSE part is calculated exactly, avoing a ``1-.''.
.logExact
normally not set by the user: whether in determining slots d,p,q, we make particular use of a logarithmic representation to enhance accuracy.
Symmetry
you may help Rin calculations if you tell it whether the distribution is non-symmetric (default) or symmetric with respect to a center; in this case use Symmetry=SphericalSymmetry(center).
Details

Typical usages are AbscontDistribution(r) AbscontDistribution(r = NULL, d) AbscontDistribution(r = NULL, d = NULL, p) AbscontDistribution(r = NULL, d = NULL, p = NULL, d) AbscontDistribution(r, d, p, q) Minimally, only one of the slots r, d, p or q needs to be given as argument. The other non-given slots are then reconstructed according to the following scheme: ccccl{ r d p q proceding - - - - excluded - + - - p by .D2P, q by .P2Q, r by q(runif(n)) - - + - d by .P2D, q by .P2Q, r by q(runif(n)) - + + - q by .P2Q, r by q(runif(n)) - - - + p by .Q2P, d by .P2D, r by q(runif(n)) - + - + p by .Q2P, r by q(runif(n)) - - + + d by .P2D, r by q(runif(n)) - + + + r by q(runif(n)) + - - - call to RtoDPQ + + - - p by .D2P, q by .P2Q + - + - d by .P2D, q by .P2Q + + + - q by .P2Q + - - + p by .Q2P, d by .P2D + + - + p by .Q2P + - + + d by .P2D + + + + nothing } For this purpose, one may alternatively give arguments low1 and up1 (NULL each by default, and determined through slot q, resp. p, resp. d, resp. r in this order according to availability), for the (finite) range of values in the support of this distribution, as well as the possibly infinite theoretical range given by arguments low and up with default values -Inf, Inf, respectively. Of course all other slots may be specified as arguments.
