Sarantopoulos (2003) described the development and the validation of a decision tree, which aims to discriminate between good and bad accounts of the customers of a particular retailer based on a sample of orders placed between certain periods of time. Lemmens and Croux (2006) explored the bagging and boosting classification techniques which significantly improved the accuracy in predicting churn. Lima et al., (2009) showed how the domain knowledge can be incorporated in the data mining process for churn prediction by analysing a decision table extracted from a decision tree or rule-based classifier.
