Description Objects from the Class Slots Methods Note Author(s) See Also Examples
Multivariate skew-elliptically contoured distributions
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. They can also obtained from an object generated
by selm
using the function extractSEDdistr
.
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.

See makeSECdistr
for a detailed description of
family
and dp
.
Note that here methods mean
and vcov
are not applied
to data or to a fitted model, but to a probability
distribution instead, of which they provide the mean (vector) value
and the variance-covariance matrix. If methods mean
and vcov
are applied to a distribution for which the mean or the variance do
not exist, a NULL
value is returned and a warning message
is issued.
