`CompoundDistribution`

-class is a class to formalize
compound distributions; it is a subclass to
class `UnivarMixingDistribution`

.

Objects can be created by calls of the form
`new("CompoundDistribution", ...)`

.
More frequently they are created via the generating function
`CompoundDistribution`

.

`NumbOfSummandsDistr`

Object of class

`"DiscreteDistribution"`

, the frequency distribution.`SummandsDistr`

Object of class

`"UnivDistrListOrDistribution"`

, that is, either of class`"UnivarDistrList"`

(non i.i.d. case) or of class`"UnivariateDistribution"`

(i.i.d. case); the summand distribution(s).`mixCoeff`

Object of class

`"numeric"`

: a vector of probabilities for the mixing components.`mixDistr`

Object of class

`"UnivarDistrList"`

: a list of univariate distributions containing the mixing components; must be of same length as`mixCoeff`

.`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`

Object of class

`"function"`

: generates random numbers`d`

fixed to

`NULL`

`p`

Object of class

`"function"`

: cumulative distribution function`q`

Object of class

`"function"`

: quantile function`.withArith`

logical: used internally to issue warnings as to interpretation of arithmetics

`.withSim`

logical: used internally to issue warnings as to accuracy

`.logExact`

logical: used internally to flag the case where there are explicit formulae for the log version of density, cdf, and quantile function

`.lowerExact`

logical: used internally to flag the case where there are explicit formulae for the lower tail version of cdf and quantile function

`Symmetry`

object of class

`"DistributionSymmetry"`

; used internally to avoid unnecessary calculations.

Class `"UnivarMixingDistribution"`

class `"UnivarDistribution"`

by class `"UnivarMixingDistribution"`

,
class `"Distribution"`

by class `"UnivariateDistribution"`

.

- show
`signature(object = "CompoundDistribution")`

prints the object- SummandsDistr
`signature(object = "CompoundDistribution")`

returns the corresponding slot- NumbOfSummandsDistr
`signature(object = "CompoundDistribution")`

returns the corresponding slot

There is a coerce method to coerce objects of class `"CompoundDistribution"`

to
class `UnivarLebDecDistribution`

; this is done by a simple call to `simplifyD`
