Marketing - MaxDiff - Diagnostic - Parameter Statistics Table

Produces a table of parameter statistics for both Marketing - MaxDiff - Latent Class Analysis and Marketing - MaxDiff - Hierarchical Bayes outputs.

With latent class analysis, this is a table containing parameter estimates and significance-testing statistics for the class size parameters and alternative parameters for each class. Note that the alternative parameters differ from those shown in the MaxDiff LCA output as those in the output have been transformed to have a mean of zero per class, and include the parameter for the first alternative, whereas the ones shown in this table are untransformed and the parameter for the first alternative is absent due to dummy coding.

With hierarchical Bayes, this is a table containing sample statistics 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

The table below shows parameter statistics from a Marketing - MaxDiff - Latent Class Analysis output:

The next table shows parameter statistics from a Marketing - MaxDiff - Hierarchical Bayes output:

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 in the parameter statistics table. In addition, class size parameters will also be displayed. If this attempt is unsuccessful, the parameter statistics table will not be able to be shown.

How to apply this QScript

• Start typing the name of the QScript into the Search features and data box in the top right of the Q window.
• Click on the QScript when it appears in the QScripts and Rules section of the search results.
