Class Definition: ClusterCriterion

statistics: obj = ClusterCriterion (x, clust, criterion)

A clustering evaluation object as created by evalclusters.

ClusterCriterion is a superclass for clustering evaluation objects as created by evalclusters.

List of public properties:

ClusteringFunction

a valid clustering funtion name or function handle. It can be empty if the clustering solutions are passed as an input matric.

CriterionName

a valid criterion name to evaluate the clustering solutions.

CriterionValues

a vector of values as generated by the evaluation criterion for each clustering solution.

InspectedK

the list of proposed cluster numbers.

Missing

a logical vector of missing observations. When there are NaN values in the data matrix, the corresponding observation is excluded.

NumObservations

the number of non-missing observations in the data matrix.

OptimalK

the optimal number of clusters.

OptimalY

the clustering solution corresponding to OptimalK.

X

the data matrix.

List of public methods:

addK

add a list of numbers of clusters to evaluate.

compact

return a compact clustering evaluation object. Not implemented

plot

plot the clustering evaluation values against the corresponding number of clusters.

Source Code: ClusterCriterion

Method: addK

ClusterCriterion: obj = addK (obj, K)

Add a new cluster array to inspect the ClusterCriterion object.

Method: compact

ClusterCriterion: obj = compact (obj)

Return a compact ClusterCriterion object (not implemented yet).

Method: plot

ClusterCriterion: plot (obj)
ClusterCriterion: h = plot (obj)

Plot the evaluation results.

Plot the CriterionValues against InspectedK from the ClusterCriterion, obj, to the current plot. It can also return a handle to the current plot.
