Idtqda contains the results of Quadratic Discriminant Analysis for the interval data
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.
Matrix with the mean vectors for each group
A three-dimensional array. For each group, g, scaling[,,g] is a matrix which transforms interval-valued observations so that within-groups covariance matrix is spherical.
Vector of half log determinants of the dispersion matrix.
Levels of the grouping factor
Configuration case of the variance-covariance matrix: Case 1 through Case 4
signature(object = "Idtqda"): Classifies interval-valued observations in conjunction with qda.
signature(object = "Idtqda"): show S4 method for the Idtqda-class
signature(object = "Idtqda"): Returns the configuration case of the variance-covariance matrix
