CHAPTER 3 Flashcards
1
Q
Efficient designs
A
- level balance
- orthogonality
- minimal level overlap
- utility balance
2
Q
Level balance
A
Levels occur with equal frequencies
3
Q
Orthogonality
A
Frequency of appearance of two different attributes = product of mg frequencies
4
Q
Minimal level overlap
A
Prob that an att repeats itself is as small as possible
5
Q
Utility balance
A
Choice options in a choice set have similar utilities
6
Q
Bayesian efficient design
A
- construct both choice options and choice experiments simultaneously
- generate efficient design
- use prior info on utility to avoid uninformative choice sets
7
Q
Factorial designs
A
- full factorial design (not practical)
- fractional factorial design (use orhogonal subset of possible combinations of attribute levels. We have to choose a subset of treatments)
