the dendrogram; similar clusters were shown for biovars of B. melitensis and for biovars of B. suis. Brucella ovis, B. canis, and B. neotomae differed from each other and from B. abortus, B. melitensis, and B. suis.

Chapter 8 Cluster Analysis SPSS - Cluster Analysis

The Dendrogram provides information similar to that covered in the icicle plot but features, in addition, a relative measure of the magnitude of differences between variables or clusters at each step of the process.

Clustering methods:

We may do so based on •A threshold distance (dissimilarity) level we are willing to "tolerate"within a cluster •Looking for obvious "leaps"in distance as we move along the dendrogram •Looking for an obvious "bend"in distance as we move along the dendrogram In fact, if we are fairly confident that ...
