INDSCAL for BP data by year
whichbest represent the corresponding dissimilarities for that individual. Hence the
acronym INDSCAL - INdividual Differences SCALing.
Let there be n objects under study and N subjects producing the dissimilarities.
Let the dimension of the spaces be p and the points in the group stimulus space be
denotedby x
