Marketing - MaxDiff - Diagnostic - Posterior Intervals Plot

Takes a MaxDiff hierarchical Bayes output created from Marketing - MaxDiff - Hierarchical Bayes and produces posterior intervals of the mean and standard deviation parameters for the distribution from which individual coefficients are sampled. For more information on how to interpret this output, see this blog post.

Example

Technical details

Whenever hierarchical Bayes analysis is run with multiple classes, an attempt will be made to match class labels between chains (note that it is often not possible to match class labels). If this succeeds, or if only one chain was specified, one set of mean and standard deviation parameters will be shown for each class. If this attempt is unsuccessful, the posterior intervals will not be able to be displayed.
