Advanced MaxDiff Aggregate Methodology
The Advanced MaxDiff Aggregate test is a great way to compare many alternatives without overwhelming respondents by asking them to read and consider all items at once. It takes a list of your items to be compared, and shows them in a balanced order to each respondent several items at a time.
How it works
The method is focused on collecting general aggregate information, without the intention to obtain individual-level estimates. In typical settings respondents would see 3-5 screens. In deciding which items to show on the next screen of the MaxDiff, the system focuses on ensuring equal coverage of pairs of items among all respondents. In other words, items are chosen randomly, with bias toward pairs of items that were seen less frequently overall across respondents. The core analysis of respondents' preferences is performed by Maximum Likelihood Multinomial Logit model. |
