Citations in the corpus
- Has brand loyalty declined? A longitudinal analysis of repeat purchase behavior in the UK and the USA (2015, methodology): “To control for the confounding factors such as category-level purchasing and changes in brand share, we use the Dirichlet multinomial model (Goodhardt et al., 1984) to measure loyalty.”
- Scalable Recommendation with Poisson Factorization (2013, background): “It implicitly assumes that each user consumes a negative-binomial number of items—a heavy-tailed distribution that is known to fit user activity well [12]–and this forces it to down-weight the contribution of the items”
- Model-Based Purchase Predictions for Large Assortments (2016, methodology): “The Dirichlet-Multinomial (DM) model (Jeuland et al., 1980; Goodhardt et al., 1984) is a known model-based approach to capture heterogeneity in purchase behavior.”
- Conceptualizing and measuring brand salience (2004, methodology): “…supported by the modelling of the relationship between initial response levels and repeat rates using a derivation of the NBDDirichlet model (Rungie and Dall’Olmo Riley, 1999) – a theory which describes the probability distributions of brand choice (Ehrenberg et al., 2000b; Goodhardt et al., 1984).”
