Module 1 -- Cluster Analysis: Partitioning
Programs require input from amat.dat with a matrix of pairwise dissimilarities/distances and a first line containing the number of objects. User will be prompted for form of matrix, "1" for half matrix and "2" for full n x n matrix. Maximum number of objects is 250. User is also prompted for desired number of clusters. Programs output to results file.
Y Chapter 3 -- Minimum-Diameter Partitioning
bbdiam.for (minimizes maximum within-cluster diamter), bbdisum.for (minimizes sum of cluster diamters) Both programs require the number of partitions to range from 2 to 20)
Y Chapter 4 -- Minimum Within-Cluster Sums of Dissimilarities
bbwcsum.for Number of partitions is limitied to 10. However, a choice of 5 or 6 would be prudent for practical cases.
Y Chapter 5 -- Minimum Within-Cluster Sums of Squares
bbwcss.for Input matrix should contain squared Euclidean distances.
Y Chapter 6 -- Multiobjective Partitioning
bbbiwcss.for Reads a second input matrix, bmat.dat.
Module 2 -- Seriation
Y Chapter 8 -- Dominance Index
Y Chapter 9 -- Gradient Indices
urg.for, urcg.for, wrg.for, wrcg.for
Y Chapter 10 -- Unidimensional Scaling
inward.for (alternating branching from ends to middle; enhancements detailed in Brusco & Stahl, 2004), forward.for
Y Chapter 11 -- Multiobjective Seriation
Module 3 -- Variable/Feature Selection
Y Chapter 13 -- Variable Selection for Cluster Analysis
