Prohibitions

Top  Previous  Next

 

Prohibitions keep specific attribute level combinations from being used in the market simulator.  This is to keep the user from simulating product concepts that were originally prohibited from showing to respondents within the market simulator.

 

Each row in the prohibitions grid allows you to specify one attribute level for each attribute.

 

Examples:

 

Partial Concept Combination: Imagine there are four attributes in your conjoint analysis study and you prohibited attribute 1 level 1 from showing with attribute 2 level 1 when you fielded the study.  To prohibit users of the market simulator from simulating choices for product concepts with the prohibited combination, you would specify:

 

 

Attribute 1

Attribute 2

Attribute 3

Attribute 4


1

1

 

 

+





 

Full Concept Combination: Imagine you prohibited levels 1, 2, 3, 2 from appearing across attribute 1 through 4 when you fielded the study.  To prohibit users of the market simulator from simulating choices for product concepts with the prohibited combination, you would specify:

 

 

Attribute 1

Attribute 2

Attribute 3

Attribute 4


1

2

3

2

+





 

Across Concept Combination: Imagine you prohibited Attribute 1 level 1 with Attribute 2 level 1 from ever appearing in competition with Attribute 1 level 1 with Attribute 2 level 2.  You specify these prohibitions across two different rows.  Then, you select both rows and click the Link button.  (More than one row may be linked.)
