"IdtMxNDE" contains the results of a mixture Normal model maximum likelihood parameter estimation, with the four different possible variance-covariance configurations. "IdtMxtNDE" is an union of classes "IdtMxNDE" and "IdtMxNDRE", the later one containing the results of mixture Normal model parameter estimation by robust methods.
Hmcdt
:Indicates whether we consider an homocedastic (TRUE) or a hetereocedasic model (FALSE)
mleNmuE
:Matrix with the maximum likelihood mean vectors estimates by group (each row refers to a group)
mleNmuEse
:Matrix with the maximum likelihood means' standard errors by group (each row refers to a group)
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 formed by a "N", indicating a Normal model, followed by the configuration (Case 1 through Case 4)
ModelType
:Inherited from class "IdtE"
. Indicates the model; always set to "Normal" in objects of the IdtMxNDE 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"

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 "IdtMxNDE"
Ngrps
:Inherited from class "IdtMxE"
. Number of mixture components
signature(x = "IdtMxtNDE")
: Linear Discriminant Analysis using the estimated model parameters.
signature(x = "IdtMxtNDE")
