Similarities Functions
Georges Le Calvé · COMPSTAT · 1988
The main problem in data analysis is the problem of the representation of this data by a visuable display understandable by every body ; such are, for example, hierarchical classification, additive tree, Euclidean representation. With this end in view, what is really analysed is not exactly the data but relations between them, namely similarities or dissimilarities. It is interesting to quote that the representations are mostly read in terms of dissimilarities, while they are constructed in terms of similarities. It is then very important to study the relations between these two kinds of association coefficients.
