A is Aesthetics (which may include weight, exotic materials, design)
E is Emotional status of purchaser
1. Which variables are missing in f( )
2. What scaling should be assigned to each
3. Is this linear and additive or are some terms non-linear?
4. How would we normalise this into a scale
Discuss.
