Quantlet: wardcont
Description: performes Ward's hierarchical cluster analysis of the rows as well as of the columns of a contingency table including the multivariate graphic using the correspondence analysis; makes available the factorial coordinates of the row points and column points (scores)

Usage: cw = wardcont (x, k, l)
Input:
x n x p matrix of n row points to be clustered (the elements must be >= 0, with positive marginal sums)
k scalar the maximum number of clusters of rows
l scalar the maximum number of clusters of columns
Output:
cw.y n x l matrix correspondence analysis scores of the row points (l = min(n-1,p-1)
cw.z p x l matrix: correspondence analysis scores of the column points
cw.r n x 1 matrix: Partition of n points into k clusters
cw.c p x 1 matrix: Partition of p points into l clusters

Example:

; load the library xclust

library ("xclust")

; generate a data set

x = #(4, 4, 25, 18, 10)~#(2, 3, 10, 24, 6)~#(3, 7, 12, 33, 7)~#(2, 4, 4, 13, 2)

; apply the ward method

cw = wardcont(x, 3, 4)

Result:

produces three displays with the ward analysis for the rows,

for the columns and for both.
