IBM SPSS Conjoint
IBM® SPSS® Conjoint includes procedures that can help researchers:
- Design an orthogonal array of product attribute combinations using ORTHOPLAN, a design generator.
- Produce and print cards that study respondents can use to sort, rank or rate alternative products.
- Analyze research data using conjoint analysis, a specially tailored version of regression.

The output for the orthogonal design has one row for each profile, with the factors displayed as columns.
A footnote lets the experimenter--but not the other test subjects-- know which cases, if any, are holdouts.
This table gives the predicted probabilities of choosing each of the simulation cases as the most preferred one, under three different probability-of-choice models.
