Technical Details for MaxDiff Utility Calculations

Input data

This QScript uses data from individual-level parameter means from a MaxDiff experiment. The variables should be combined into a Number - Multi question that has the string Individual-Level Parameter Means in the name. The individual-level parameters question can be generated in Q from a segmentation of a ranking question (by right-clicking a node of the tree and selecting Save Individual-Level Parameter Means and Standard Deviations).

Alternatively, the individual-level parameter means can be computed externally and imported into Q as part of a larger data set. In this case:

• The variables should be combined as a Number - Multi question.
• The text Individual-Level Parameter Means should be included in the question name.

Outputs

A new Number - Multi question is generated in the project, and a table is added to the report to show the average of the computed values.
