Dynamics of signature distance matrices. Distance matrices were obtained from the RAG1 vertebrate study (see below). There are two types of criteria: metric (for example Vaf, stress) and topological (Arboricity, rate of well designed quadruples, rate of elementary quadruples). Vaf (variance accounted for): quadratic difference divided by the variance of distance. Rate of well designed quadruples: quadruples having the same topology according the two distance matrices; Rate of elementary quadruples, Arboricity; see [26]. On the y-axis, the criteria values obtained from the method of distance are plotted. For the stress, this value is indicated also by a dot line.
