The HierarchicalClusterAnalysis
node in SciCraft has the
following node arguments:
- Input ports:
X: Matrix containing input data.
- Input parameters:
- metric: String specifying the metric used in the analysis
(details below).
- method: String specifying the method used in the analysis
(details below).
- rows: String specifying if you should cluster over the rows
or the columns in the input data matrix X.
- Output ports:
- Clustering: R-Object containing the
following elements:
- height: Vector with the distances between
merging clusters at the successive stages.
: the agglomerative coefficient, measuring the
clustering structure of the dataset.
- merge: Matrix where row
of 'merge'
describes the merging of clusters at step
of the
clustering. If a number
in the row is negative,
then the single observation
is merged at this
stage. If
is positive, then the merger is with
the cluster formed at stage
of the algorithm.
- order: Vector giving a permutation of the
original observations to allow for plotting, in the
sense that the branches of a clustering tree will
not cross.
