summary.SECdistr: Summary of a SEC distribution object

Description

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 are produced by makeSECditr.

Usage

## S3 method for class 'SECdistrUv':
summary(object, cp.type = "auto", probs)
## S3 method for class 'SECdistrMv':
summary(object, cp.type = "auto")

Arguments

object

an object of class "SECdistrUv" or "SECdistrMv".

cp.type

a character string to select the required variance of CP parameterization; possible values are "proper", "pseudo", "auto" (default). For a description of these codes, see

probs

in the univariate case, a vector of probabilities for which the corresponding quantiles are required.

Value

• A list with the following components:
• family
  name of the family within the SEC class, character
• dp
  DP parameters, list or vector
• name
  the name of the distribution, character string
• compNames
  in the multivariate case, the names of the components
• cp
  CP parameters, list or 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 non-parametric variants, and more).

Examples

f3 <- makeSECdistr(dp=c(3,2,5), family="SC")
summary(f3)
print(s <- summary(f3, probs=(1:9)/10))
print(slot(s, "aux")$mode)
#
dp3 <- list(xi=1:3, Omega=toeplitz(1/(1:3)), alpha=c(-3, 8, 5), nu=6)
st3 <- makeSECdistr(dp=dp3, family="ST", compNames=c("U", "V", "W"))
s <- summary(st3)
print(slot(s, "aux")$delta.star)
