Utilities plots are the oldest data visualization developed for conjoint analysis. They first appeared in the work of early leading light Paul Green, who referred to them as plots of part-worth. The plot has a number of nice features. First, it allows us to easily see the relative importance of the different attributes, which is defined as the difference between the utility of the highest and lowest levels of each attribute. Second, it makes it easy to see the relative appeal of different attribute levels. For more reading on them see our blog post here. This article describes how to go from a choice model output created in Displayr:
To a utilities plot based on the choice model attribute utilities:
- A document containing one or more choice model outputs created in Displayr.
