A command that calculates the "additive constant" from the selected Dissimilarity.
Distances dij will be obtained from dissimilarities δij according to:
|distanceij = dissimilarityij + additiveConstant|
We use a procedure by Cailliez (1983) to solve the "additive constant problem", i.e. find the smallest additiveConstant such that all distanceij in the above equation have a Euclidean representation.
