tclusticsol.object {fsdaR}

Objects returned by the function tclustICsol

Description

An object of class tclusticsol.object holds information about the result of a call to tclustICsol.

Value

The functions print() and summary() are used to obtain and print a summary of the results. An object of class tclusticsol 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

MIXMIXbs

a matrix of lists of size NumberOfBestSolutions-times-5 which contains the details of the best solutions for MIXMIX (BIC). Each row refers to a solution. The information which is stored in the columns is as follows.

• 1st col = value of k for which solution takes place

• 2nd col = value of c for which solution takes place;

• 3rd col = a vector of length d which contains the values of c for which the solution is uniformly better.

• 4th col = a vector of length d + r which contains the values of c for which the solution is considered stable (i.e. for which the value of the adjusted Rand index (or the adjusted Fowlkes and Mallows index) does not go below the threshold defined in input option ThreshRandIndex).

• 5th col = string which contains 'true' or 'spurious'. The solution is labelled spurious if the value of the adjusted Rand index with the previous solutions is greater than ThreshRandIndex.

Remark: the field MIXMIXbs is present only if whichIC=ALL or whichIC="MIXMIX".

MIXMIXbsari

a matrix of adjusted Rand indexes (or Fowlkes and Mallows indexes) associated with the best solutions for MIXMIX. A matrix of size NumberOfBestSolutions-times-NumberOfBestSolutions whose i,j-th entry contains the adjusted Rand index between classification produced by solution i and solution j, i,j=1,2, ...,NumberOfBestSolutions.

Remark: the field MIXMIXbsari is present only if whichIC=ALL or whichIC="MIXMIX".

ARIMIX

a matrix of adjusted Rand indexes between two consecutive value of c. Matrix of size k-by-length(cc)-1. The first column contains the ARI indexes between cc[2] and cc[1] given k. The second column contains the the ARI indexes between cc[3] and cc[2] given k.

Remark: the field ARIMIX is present only if whichIC=ALL or whichIC="MIXMIX" or whichIC="MIXCLA".

MIXCLAbs

has the same structure as MIXMIXbs but referres to MIXCLA.

Remark: the field MIXCLAbs is present only if whichIC=ALL or whichIC="MIXCLA".

MIXCLAbsari

has the same structure as MIXMIXbsari but referres to MIXCLA.

Remark: the field MIXMIXbsari is present only if whichIC=ALL or whichIC="MIXCLA".

CLACLAbs

has the same structure as MIXMIXbs but referres to CLACLA.

Remark: the field CLACLAbs is present only if whichIC=ALL or whichIC="CLACLA".

CLACLAbsari

has the same structure as MIXMIXbsari but referres to CLACLA.

Remark: the field CLACLAbsari is present only if whichIC=ALL or whichIC="CLACLA".

ARICLA

a matrix of adjusted Rand indexes between two consecutive value of c. Matrix of size k-by-length(cc)-1. The first column contains the ARI indexes between cc[2] and cc[1] given k. The second column contains the the ARI indexes between cc[3] and cc[2] given k.

Remark: the field ARICLA is present only if whichIC=ALL or whichIC="CLACLA".
