No full textMultiple-record systems estimation using latent class models
No full textCapture–recapture methods (also referred to as ‘multiple-record systems’) have been widely used in enumerating human populations in the fields of epidemiology and public health. In this article, we introduce latent class models into multiple-record systems to account for unobserved heterogeneity in the population. Two approaches, the full and the conditional likelihood, are proposed to estimate the unknown population abundance. We also suggest rules to diagnose identifiability of the proposed latent class models. The methodologies are illustrated by two real examples: the first is to count the undercount of homelessness in the Adelaide central business district, and the second concerns the incidence of diabetes in a small Italian town.
Is there more information in best-worst choice data?: using the attitude heterogeneity structure to identify consumer segments

No full textThis study examines the impact of actual price increases on customer retention in a service context and how the effect of a price increase is moderated by both tenure and breadth of the customer's relationship. The study finds that tenure is associated with lowered customer sensitivity to price increases as well as having a favorable direct effect on customer retention rates. The study also finds that relationship breadth can exacerbate the adverse effect of price increases on customer retention. Finally, relationship breadth is found to have a favorable direct effect on retention rates only among newer customers. The managerial implication is that marketers must pay extra attention to short-tenure and broad-breadth customers when implementing price increases. The study represents a unique contribution to the service marketing literature, which to date reports little research examining the effect of actual price changes on consumer behavior.
