Technical Features of R-sw Conjoint (Juster)

What does R-sw Conjoint do?

  • it provides adjustment of shares for overstatement via the Juster’s 11-point purchase probability scale.


  • share adjustment is directly applied to the product(s) for which the Juster question is asked, and indirectly applied to the other market players;
  • it is possible to use either the standard Juster probability coefficients or to assign ad-hoc ones to reflect specific project needs;
  • data can be easily imported and outcomes can be exported as CSV/text files.

Support, Manual and Examples:

  • technical support and statistical consulting is available free of charge (within reasonable limits);
  • an ‘html’ manual is provided with a detailed description of all available functions;
  • full working examples are provided to help the User to become familiar with the package. These examples can be easily adapted by the User for new projects.

Note: this is a pure analysis tool, therefore data must be collected through an external source (such as a CAWI, CAPI or PAPI system).
