Idtlda-class: Class "Idtlda"

In MAINT.Data: Model and Analyse Interval Data

Class "Idtlda"

Description

Idtlda contains the results of Linear Discriminant Analysis for the interval data

Slots

prior:

Prior probabilities of class membership; if unspecified, the class proportions for the training set are used; if present, the probabilities should be specified in the order of the factor levels.

means:

Matrix with the mean vectors for each group

scaling:

Matrix which transforms observations to discriminant functions, normalized so that within groups covariance matrix is spherical.

N:

Number of observations

CovCase:

Configuration case of the variance-covariance matrix: Case 1 through Case 4

Methods

predict

signature(object = "Idtlda"): Classifies interval-valued observations in conjunction with lda.

show

signature(object = "Idtlda"): show S4 method for the IDdtlda-class

CovCase

signature(object = "Idtlda"): Returns the configuration case of the variance-covariance matrix
