Class "IdtMxNandSNDE"

Share:

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.

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

Extends

Class "IdtMxE", directly. Class "IdtE", by class "IdtMxE", distance 2.
