Multidimensional scaling

Baglioni, Tony

All,

 

I want to perform a MDS and I’m not sure of the format for my data.  I wish to see the results as a function of Brand rather than as a function of Characteristic.  Currently, the data are grouped by Brand with the Characteristics in the columns.  What should my data look like?

 

Thanks,

Tony

Multidimensional scaling --> multidimensional unfolding

Busing, Frank
Dear Tony.
 
Depending on the kind of measurements,
and knowing you have two sets of objects (brands and characteristics),
I would suggest you try PREFSCAL.
It is an unfolding program.
This way, you can visualize both sets in one configuration.
 
I need more information for a more detailed advice.
 
Good luck, Frank.
