Hi,
If I use an alternative specific design with 6 brands and I specify a unique price attribute for brand 1 and a second unique price attribute for brand 2 plus another (third) unique price attribute for brands 3 to 6.. Is it necessary to think about interaction terms in this case as I should when using a conditional pricing approach?
My guess is that with an alternative specific approach the three different price slopes already capture the interaction effects.
Can you please help me?
Regards
Mathew
