Thank you for your answer, With regard to what you told, I would just need a few precisions, in: > to compare INDSCAL solutions only permutations and scalings of solutions are > authorized.
does ''scalings'' involve that the dilatations along the dimensions are only allowed according to a same factor ? Concerning the Tucker coefficient of congruence: >... where a and b are two vectors of coordinates form the two different >Indscal solutions. By ``vectors'', did you also include ''arrays ''( of size nbpoints*nbdimensions in the present case) ? Or must the calculcation be done separately for the couples of dimensions (dimension 1 config1 ---> dimension 1 config2, (dimension 2 config1 -----> dimension 2 config2) Does the comparison via this coefficient imply that the 90°rotations, reflections, dilatations must be all proceeded beforehand ? Sorry if these questions could appear trivial..:-) Best regards, Arnaud. ---------------------------------------------- CLASS-L list.
