The Ohlson model is evaluated using quarterly data from stocks in the Dow Jones Index. A hierarchical Bayesian approach is developed to simultaneously estimate the unknown coefficients in the time series regression model for each company by pooling information across firms. Both estimation and prediction are carried out by the Markov chain Monte Carlo (MCMC) method. Our empirical results show t...

Business Intelligence (BI) requires the acquisition and aggregation of key pieces of knowledge from multiple sources in order to provide valuable information to customers or feed statistical BI models and tools. The massive amount of information available to business analysts makes information extraction and other natural language processing tools key enablers for the acquisition and use of tha...

This paper presents a problem-based learning (PBL) approach developed to introduce students to business intelligence. Using a simulation game approach called ERPsim, students must manage the operation of a distribution company under an ERP system. The transaction data are made available to students through a database called ERPsim BI which is updated dynamically during the game. Learners must b...

In this paper, we introduce the notion of a bi-cooperative game with fuzzy bi-coalitions and discuss the related properties. In real game theoretic decision making problems, many criteria concerning the formation of coalitions have bipolar motives. Our model tries to explore such bipolarity in fuzzy environment. The corresponding Shapley axioms are proposed. An explicit form of the Shapley valu...

the decomposition $gamma=bh$ of a group $gamma$ into a subset $b$ and a subgroup $h$ of $gamma$ induces, under general conditions, a group-like structure for $b$, known as a gyrogroup. the famous concrete realization of a gyrogroup, which motivated the emergence of gyrogroups into the mainstream, is the space of all relativistically admissible velocities along with a binary operation given by t...

Abstract: An insurance company offers an insurance contract (p, K), consisting of a premium p and a deductible K. In this paper, we consider the problem of choosing the premium optimally as a function of the deductible. The insurance company is facing a market of N customers, each characterized by their personal claim frequency, α, and risk aversion, β. When a customer is offered an insurance c...

Business Intelligence (BI) and Business Analytics (BA) are very fast moving fields which have evolved greatly from fields such as Data Mining and Knowledge Discovery in Databases (KDD). Today the focus of much research in BI centers on the notion of the BI software platform and its analytic capabilities. The implications of the term business intelligence are much broader, however, and indicate ...
