Distribution-class

Class "Distribution"

The Distribution-class is the mother-class of class UnivariateDistribution.

Objects can be created by calls of the form new("Distribution").

img: Object of class "rSpace": the space of the image
param: Object of class "OptionalParameter": the parameter
r: Object of class "function": generates random numbers
d: Object of class "OptionalFunction": density function
p: Object of class "OptionalFunction": cumulative distribution function
q: Object of class "OptionalFunction": 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.

img: signature(object = "Distribution"): returns the space of the image
param: signature(object = "Distribution"): returns the parameter
r: signature(object = "Distribution"): returns the random number generator
d: signature(object = "Distribution"): returns the density function
p: signature(object = "Distribution"): returns the cumulative distribution function
q: signature(object = "Distribution"): returns the quantile function
.logExact: signature(object = "Distribution"): returns slot .logExact if existing; else tries to convert the object to a newer version of its class by conv2NewVersion and returns the corresponding slot of the converted object.
.lowerExact: signature(object = "Distribution"): returns slot .lowerExact if existing; else tries to convert the object to a newer version of its class by conv2NewVersion and returns the corresponding slot of the converted object.
Symmetry:: returns slot Symmetry if existing; else tries to convert the object to a newer version of its class by conv2NewVersion and returns the corresponding slot of the converted object.
