So, we will go with the selected 16 combinations and their rankings from a survey. Then run Conjoint Analysis and wait for the results giving interesting insights. What is a Conjoint Analysis? And let's go ahead and run that. The attributes and the levels of each beer brand was used to create a binary matrix, as shown below: The Partworth utilities for each respondent are cross multiplied with the above binary matrix, and then exponentiated. -- https://sawtoothsoftware.com/conjoint-analysis/acbc. How does the consumer value different attributes (function, benefit and features etc.) It is a commonly used statistical technique for modelling consumption decisions and market shares of products when new products are released.
