Univariate skew-elliptically contoured distributions
Objects can be created by a call to function makeSECdistr
when its argument dp
is a vector. They can also obtained from
an object generated by selm
using the function extractSEDdistr
.
family
:a character string which selects the parametric family; currently, possible values are: "SN", "ESN", "ST", "SC".
dp
:a numeric vector of parameters; its length depends
on the selected family
.
name
:a character string with name of the distribution.
signature(object = "SECdistrUv")
: ...
signature(x = "SECdistrUv")
: ...
signature(object = "SECdistrUv")
: ...
signature(x = "SECdistrUv")
: ...
signature(object = "SECdistrUv")
: ...
See makeSECdistr
for a detailed description of family
and dp
.
Unlike various other packages, methods mean
and sd
here are
not targeted to data or to a fitted model, but to a probability
distribution instead, of which they provide the mean value
and the standard deviation. If these methods are applied
to a distribution of which the mean or the variance do not exist,
a NULL
value is returned and a warning message is issued.
