I've run a cluster analysis with Jaccard distance and Ward's method. The
clustering height (located on the left of the dendrogram) is not scaled to
the distance function because the height values range from 0 to 3.5 in
increments of 0.5. In Oksanen's Vegan tutorial, the examples of the cluster
dendrograms show height values that appear to be the Bray distance values
(with various linkage methods) because the height values are less than 1.
I'm not sure what my height values reflect. Is the clustering height
associated with Wards? Can the the height values be rescaled to the Jaccard
values?
Many thanks,
Leigh
