p. 42 | Classification based on Nominal Variables, Cowgill 1982 | Nominal variables and Similar Coefficient: Give to each variable equal weight. Any similarity coefficient has to be monotonic function of the number of variables on which the two objects share individual value. For two variables equally weighted the similarity coefficient can assume just one of the 3 values: High: the objects have identical values on both variables Medium: the objects have identical values on exactly one variable Low: the objects have different values for both variables 1982 article |
Hodson 1977 | Hodson stresses on both internal cohesion and external isolation for a good object-cluster type is to say that for any member of a good type, the frequency distribution of similarities to all other objects in the assemblage should be bimodal or polymodal. |
p. 36 | Spaulding 1977 | Association of variables: if knowledge of the state of variable X for an object is directly relevant for stating the probabilities of the various possible state of variable Y for the same objects we say that X and Y are associated. If knowledge of the state of variable Z for an object is relevant for saying how the state of X relates to the state of Y we say that there is an interaction between Z, X and Y. |
