tclustic.object: Objects returned by the function tclustIC

Description

An object of class tclustic.object holds information about the result of a call to tclustIC.

Value

The functions print() and summary() are used to obtain and print a summary of the results. An object of class tclustic is a list containing at least the following components:

call

the matched call

kk

a vector containing the values of k (number of components) which have been considered. This vector is identical to the optional argument kk (default is kk=1:5.

cc

a vector containing the values of c (values of the restriction factor) which have been considered. This vector is identical to the optional argument cc (defalt is cc=c(1, 2, 4, 8, 16, 32, 64, 128).

alpha

trimming level

whichIC

Information criteria used

CLACLA

a matrix of size length(kk)-times-length(cc) containinig the value of the penalized classification likelihood. This output is present only if whichIC="CLACLA" or whichIC="ALL".

IDXCLA

a matrix of lists of size length(kk)-times-length(cc) containinig the assignment of each unit using the classification model. This output is present only if whichIC="CLACLA" or whichIC="ALL".

MIXMIX

a matrix of size length(kk)-times-length(cc) containinig the value of the penalized mixtrue likelihood. This output is present only if whichIC="MIXMIX" or whichIC="ALL".

IDXMIX

a matrix of lists of size length(kk)-times-length(cc) containinig the assignment of each unit using the classification model. This output is present only if whichIC="MIXMIX" or whichIC="ALL".

MIXCLA

a matrix of size length(kk)-times-length(cc) containinig the value of the ICL criterion. This output is present only if whichIC="MIXCLA" or whichIC="ALL".

Examples

 if (FALSE) {
 data(hbk, package="robustbase")
 (out <- tclustIC(hbk[, 1:3]))
 class(out)
 summary(out)
