We develop a general class of factor-analytic models for the analysis of multivariate (truncated) count data. Dependencies in multivariate counts are of interest in many applications, but few approaches have been proposed for their analysis. Our model class allows for a variety of distributions...

With recent advances in information technology, most companies are amassing extensive customer databases. The wealth of information in these databases can be useful in identifying those customers most likely to purchase a new product and in predicting when this adoption may take place. This can...

This paper introduces a general, formal treatment of dynamic constraints, i.e., constraints on the state changes that are allowed in a given state space. Such dynamic constraints can be seen as representations of "real world" constraints in a managerial context. The notions of transition,...

The service-profit chain (SPC) is a framework for linking service operations, employee assessments, and customer assessments to a firm's profitability (Heskett et al. 1994). The SPC provides an integrative framework for understanding how a firm's operational investments into service operations...

This article develops a model for the measurement of human values that, rather than obtain aggregate measurements, identifies distinct value systems within a population and classifies individuals according to them. These value systems are inferred from the stated priority rankings, obtained from...

A variant of Banker and Morey's (Banker, R. D., R. C. Morey. 1986. The use of categorical variables in data envelopment analysis. Management Sci. 32(12, December) 1613--1627.) DEA model for controllable ordinal outputs. As opposed to the original model, this version allows the comparison of a...

In a situation where several hundred new music albums are released each month, producing sales forecasts in a reliable and consistent manner is a rather difficult and cumbersome task. The purpose of this study is to obtain sales forecasts for a new album before it is introduced. We develop a...
