Decision Analyst ChoiceModelR™

ChoiceModelR™ is an open-source software package written in R language by Decision Analyst statistical programmers. It is designed to analyze data from choice modeling experiments across a wide array of industries, based on surveys of how target market consumers react to many different marketing and product stimuli at different price points (i.e., different scenarios). ChoiceModelR™ is ideal for large datasets with complex variables. This software replicates the functionality of the best commercial choice modeling programs. The program assumes that the choice modeling experiment (the data-collection phase) has been conducted and the data are ready to analyze. The software runs within the R platform and includes the following features:

  • Dependent variable may be either discrete (nominal or ordinal) or shared (continuous between zero and one).
  • Constraints may be imposed on model parameters.
  • Number of choice observations per decision maker (e.g., respondent) may vary.
  • Number of choice alternatives per choice observation may vary.

To run ChoiceModelR™, users must have a basic understanding of choice modeling and R language, and they must download R language. Both ChoiceModelR™ and R language are open source and free.
