generating functions `UnivarMixingDistribution`

`Minimum`

, `Maximum`

, `Truncate`

, and
`Huberize`

have an argument `withSimplify`

which
decides whether the respective result is filtered by/piped through a
call to `simplifyD`

.
By default this argument is set to the distr-option
`getdistrOption("simplifyD"`

(for the inspection and modification of such
global options see `distroptions`

). Depending on whether or not this
option is `TRUE`

, also arithmetic operations `"+"`

, `"*"`

, `"/"`

,
`"^"`

and group `Math`

give results filtered by/piped through a call
to `simplifyD`

.

the corresponding, possibly simplified distribution

- simplifyD
`signature(object = "AbscontDistribution")`

: returns`object`

unchanged- simplifyD
`signature(object = "DiscreteDistribution")`

: returns`object`

unchanged- simplifyD
`signature(object = "UnivarLebDecDistribution")`

: checks whether`acWeight`

or`discreteWeight`

is approximately (i.e.; up to`getdistrOption("TruncQuantile")`

) zero and if so, accordingly returns`discretePart(object)`

or`acPart(object)`

, respectively.- simplifyD
`signature(object = "UnivarMixingDistribution")`

: returns the flattened version of`object`

(using`flat.mix`

). before doing so, it checks whether any component carries weight approximately (i.e.; up to`getdistrOption("TruncQuantile")`

) one (in slot`mixCoeff`

) and if so, returns this component; else, if not all weights are below`getdistrOption("TruncQuantile")`

), it filters out those components with weight less than`getdistrOption("TruncQuantile")`

).
