IdtMxSNDE contains the results of a mixture model estimation for the Skew-Normal model, with the four different possible variance-covariance configurations.
Hmcdt:Indicates whether we consider an homocedastic location model (TRUE) or a general model (FALSE)
CovConfCases:List of the considered configurations
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 "IdtMxSNDE"
Ngrps:Inherited from class "IdtMxE". Number of mixture components
No methods defined with class "IdtMxSNDE" in the signature.
