Class "UnivarLebDecDistribution"

Description

UnivarLebDecDistribution-class is a class to formalize a Lebesgue decomposed distribution with a discrete and an absolutely continuous part; it is a subclass to class UnivarMixingDistribution.

Objects from the Class

Objects can be created by calls of the form new("UnivarLebDecDistribution", ...). More frequently they are created via the generating function UnivarLebDecDistribution.

Slots

mixCoeff

Object of class "numeric": a vector of length 2 of probabilities for the respective a.c. and discrete part of the object

mixDistr

Object of class "UnivarDistrList": a list of univariate distributions containing the a.c. and discrete components; must be of length 2; the first component must be of class "AbscontDistribution", the second of class "DiscreteDistribution".

img

Object of class "Reals": the space of the image of this distribution which has dimension 1 and the name "Real Space"

param

Object of class "Parameter": the parameter of this distribution, having only the slot name "Parameter of a discrete distribution"

r

d

fixed to NULL

p

Result is again of class "UnivarLebDecDistribution", but if option getdistrOption("withSimplify") is TRUE it is piped through a call to simplifyD, hence may also be of class AbscontDistribution or DiscreteDistribution

Internal subclass "AffLinUnivarLebDecDistribution"

To enhance accuracy of several functionals on distributions, mainly from package distrEx, there is an internally used (but exported) subclass "AffLinUnivarLebDecDistribution" which has extra slots a, b (both of class "numeric"), and X0 (of class "UnivarLebDecDistribution"), to capture the fact that the object has the same distribution as a * X0 + b. This is the class of the return value of methods

There also is a class union of "AffLinAbscontDistribution", "AffLinDiscreteDistribution", "AffLinUnivarLebDecDistribution" and called "AffLinDistribution" which is used for functionals.

Internal virtual superclass "AcDcLcDistribution"

As many operations should be valid no matter whether the operands are of class "AbscontDistribution", "DiscreteDistribution", or "UnivarLebDecDistribution", there is a class union of these classes called "AcDcLcDistribution"; in particular methods for "*", "/", "^" (see operators-methods) and methods Minimum, Maximum, Truncate, and Huberize, and convpow are defined for this class union.
