The Bayesian revolution in marketing research
This paper describes the paradigm shift that has been occurring in the statistical analysis of marketing data over the past 10 years. The new paradigm reflects a perspective on probability that was first proposed in the 18th century by Thomas Bayes, an English clergyman. These new methods of analysis offer better solutions to a wider range of marketing problems than classical statistical methods. After a brief introduction to the Bayesian view of probability, the paper discusses the potential impact of Bayesian analysis on managerial decision-making. Two case studies demonstrate the power of these methods for understanding and predicting consumer behavior.
