CL HD - Classification - Hierarchical, get number of classes

PURPOSE

Calculates number of classes for given threshold from a dendrogram. This operation only works in conjunction with hierarchical clustering output from 'CL HC' or 'CL CLA'.

USAGE

.OPERATION: CL HD

.CUTOFF THRESHOLD % (0-100): 20
[Enter the scale value at which the dendrogram will be cut/truncated. Classes with indices below the threshold will be merged. If the threshold is zero no merger is done and the classes retain their original numbers. For threshold > 0 classes are renumbered.]

.DENDOGRAM DOCUMENT FILE: DEND_CL
[Enter name of the untruncated dendrogram document file containing classification tree produced by 'CL CLA' or 'CL HC').]

.DOCUMENT FILE: DEND_NUM
[Enter the document file name which will contain number of objects belonging to each class.]

NOTES

1. To get selection doc files corresponding to the given "cutting" use command 'CL HE'.

2. To calculate averages for the classes use command 'AS DC' and selection doc files.

3. See: Classification and Clustering Summary and Classification and Clustering Tutorial for further info.
