Underreporting of purchases of port wine
In this paper, we develop a new approach for modelling underreported Poisson counts. The parameters of the model are estimated by Markov chain Monte Carlo simulation. An application to a real data set from a Portuguese marketing survey illustrates the fruitfulness of the approach. We find that purchases of bottles of port wine increase significantly with income class and the size of the household.
