Produce a summary of an object of class either
"SECdistrUv"
or "SECdistrMv"
, which refer to a univariate or a
multivariate SEC distribution, respectively. Both types of
objects can be produced by makeSECditr
.
1 2 3 4 5 
object 
an object of class 
cp.type 
a character string to select the required variance of
CP parameterization; possible values are 
probs 
in the univariate case, a vector of probabilities for which
the corresponding quantiles are required. If missing, the vector

A list with the following components:
family 
name of the family within the SEC class, character 
dp 
DP parameters, a list or a vector 
name 
the name of the distribution, character string 
compNames 
in the multivariate case the names of the components, a character vector 
cp 
CP parameters, a list or a vector 
cp.type 
the name of the selected variant of the CP set 
aux 
a list with auxiliary ingredients (mode, coefficients of skewness and kurtosis, in the parametric and nonparametric variants, and more). 
DP and CP are vectors if class(object)
is
SECdistrUv
(univariate distribution); they are lists if codeclass(object) is SECdistrMv
(multivariate distribution).
The examples below show how extract components from aux
and other slots.
