about ranges in MDS

[José Luis Ortega]

I have a question for mathematicians:

The cosine have a range [0,1] and Pearson's Coefficient [1,-1]. If i build a
matrix distance with these measures, can theses different ranges affect in a
MDS display of the data? and How? more spreading or less?

Thank you
