Marketing - MaxDiff - Save Variable(s) - Zero-Centered Utilities

Create new variables which contain the zero-centered utilities for each respondent from a MaxDiff latent class analysisMaxDiff latent class analysis, MaxDiff hierarchical BayesMaxDiff hierarchical Bayes or MaxDiff ensembleMaxDiff ensemble output. Note that the variables are the same as those from Marketing - MaxDiff - Save Variable(s) - Individual-level CoefficientsSave individual-level coefficients as the individual-level coefficients are already zero-centered. You should select the output before running this script.

Example

The script produces a SUMMARY table with the new variables:
