An Aggregate test of purchase regularity

Author: Tibrewala, Vikas ; Buchanan, BruceINSEAD Area: Marketing Series: Working Paper ; 91/19/MKT Publisher: Fontainebleau : INSEAD, 1990.Language: EnglishDescription: 15 p.Type of document: INSEAD Working PaperAbstract: In this paper a technique is presented to identify the most appropriate individual-level assumption for stochastic purchase-incidence models. The measure is able to use data from the complete histogram of purchases, and makes no assumptions about the form of heterogeneity in rates. In addition, a resampling technique is used to control for the effects of non-stationarity. Thus, the measure is free from any confounding assumptions. The performance of the technique is illustrated by application to simulated data sets. Results are reported from the application of the technique to consumer panel data
