IdtSngSNDE-class: Class IdtSngSNDE

Description

Contains the results of a single class maximum likelihood estimation for the Skew-Normal distribution, with the four different possible variance-covariance configurations.

Arguments

Slots

CovConfCases:: List of the considered configurations
ModelNames:: The model acronym, indicating the model type (currently, N for Normal and SN for Skew-Normal), and the configuration Case (C1 to C4) for the covariance matrix
ModelNames:: Inherited from class '>IdtE. The model acronym formed by a "SN", indicating a skew-Normal model, followed by the configuration (Case 1 through Case 4)
ModelType:: Inherited from class '>IdtE. Indicates the model; always set to "SkewNormal" in objects of the IdtSngSNDE class
ModelConfig:: Inherited from class '>IdtE. Configuration case of the variance-covariance matrix: Case 1 through Case 4
NIVar:: Inherited from class '>IdtE. Number of interval variables
SelCrit:: Inherited from class '>IdtE. The model selection criterion; currently, AIC and BIC are implemented
logLiks:: Inherited from class '>IdtE. The logarithms of the likelihood function for the different cases
AICs:: Inherited from class '>IdtE. Value of the AIC criterion
BICs:: Inherited from class '>IdtE. Value of the BIC criterion
BestModel:: Inherited from class '>IdtE. Indicates the best model according to the chosen selection criterion
SngD:: Inherited from class '>IdtE. Boolean flag indicating whether a single or a mixture of distribution were estimated. Always set to TRUE in objects of class IdtSngSNDE

Extends

Class '>IdtSngDE, directly. Class '>IdtE, by class '>IdtSngDE, distance 2.
