Changed reference models in proportionality analysis
  In the statistical analysis of objects, samples and populations with quantitative variables, in many occasions we are interested in knowing the proportions that exist between the different variables from a same object; if these proportions have relations of normality among them, that is to say, if in the sample are these same proportions, and finally if the deviations of concrete physical or statistical normality have meaning. The present study suggests the strategy of to use reference models for the analysis of the proportionality, using like example the studies of human proportionality from the method Phantom of Ross and Wilson and its extension towards scalable models.
