“Counting Your Customers” One by One: A Hierarchical Bayes Extension to the Pareto/NBD Model

Published: 01 May 2009 Publication History

Abstract

This research extends a Pareto/NBD model of customer-base analysis using a hierarchical Bayesian HB framework to suit today's customized marketing. The proposed HB model presumes three tried and tested assumptions of Pareto/NBD models: 1 a Poisson purchase process, 2 a memoryless dropout process i.e., constant hazard rate, and 3 heterogeneity across customers, while relaxing the independence assumption of the purchase and dropout rates and incorporating customer characteristics as covariates. The model also provides useful output for CRM, such as a customer-specific lifetime and survival rate, as by-products of the MCMC estimation.
Using three different types of databases---music CD for e-commerce, FSP data for a department store and a music CD chain, the HB model is compared against the benchmark Pareto/NBD model. The study demonstrates that recency-frequency data, in conjunction with customer behavior and characteristics, can provide important insights into direct marketing issues, such as the demographic profile of best customers and whether long-life customers spend more.
