SECdistrMv-class {sn}R Documentation

Class "SECdistrMv"

Description

Multivariate skew-elliptically contoured distributions

Objects from the Class

Objects can be created by a call to function makeSECdistr, when its argument dp is a list, or by a suitable transformation of some object of this class.

Slots

family:

a character string which identifies the parametric family; currently, possible values are: "SN", "ESN", "ST", "SC".

dp:

a list of parameters; its length depends on the selected family.

name:

a character string with the name of the multivariate variable; it can be an empty string.

compNames:

a vector of character strings with the names of the component variables.

Methods

show

signature(object = "SECdistrMv-class"): ...

plot

signature(x = "SECdistrMv-class"): ...

summary

signature(object = "SECdistrMv-class"): ...

Note

See makeSECdistr for a detailed description of family and dp. If an object of this class is manipulated by affineTransSECdistr or marginalSECdistr, the returned object is of the same class, unless the transformation leads to a univariate distribution.
