IdtMxNandSNDE-class: Class IdtMxNandSNDE

Description

IdtMxNandSNDE contains the results of a mixture model estimation; Normal an Skew-Normal models are considered, with the four different possible variance-covariance configurations.

Arguments

Slots

NMod:: Estimates of the mixture model for the Gaussian case
SNMod:: Estimates of the mixture model for the Skew-Normal case
grouping:: Inherited from class IdtMxE. Factor indicating the group to which each observation belongs to
ModelNames:: Inherited from class IdtE. The model acronym, indicating the model type (currently, N for Normal and SN for Skew-Normal), and the configuration (Case 1 through Case 4)
ModelType:: Inherited from class IdtE. Indicates the model; currently, Gaussian or Skew-Normal distributions are implemented
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 FALSE in objects of class IdtMxNandSNDE
Ngrps:: Inherited from class IdtMxE. Number of mixture components
