  1. Three statistics related to mean change (using the dynamic scale) and the Bubastis variables have been used for performing a PCA, with the objective of obtaining the relation between these two different ontology aspects. The variable representation of Fig. 7 suggests the presence of two normalised uncorrelated factors: Bubastis Activity and OQuaRE Dynamic Quality. The representation of these coordinates can be found in Fig. 7 above
