Similarity: To Dissimilarity...

A command that creates a Dissimilarity from every selected Similarity.

Setting

Maximum dissimilarity
determines the maximum dissimilarity possible. When the default value, 0.0, is chchosenmaximumDissimilarity is calculated as the maximum element in the Similarity object.

Algorithm

To obtain dissimilarities we 'reverse' similarities:

dissimilarityij = maximumDissimilaritysimilarityij

In this way the order of dissimilarities is the reverse of the order of the similarities.
