Two-group classification is a key task in decision making and data mining applications. We introduce two new mixed integer programming formulations that make use of multiple separating hyperplanes. They represent a generalization of previous piecewise-linear models that embed rules having the...

A variable selection method for constructing decision trees with rank data is proposed. It utilizes conditional independence tests based on loglinear models for contingency tables. Compared with other selection methods, our method is computationally more efficient. Moreover, our method is...

The ongoing financial and economic crisis throughout the industrialised world has spotlighted a number of significant deficiencies in corporate governance and management. The strength and composition of the management team along with effective corporate governance policy should play an important...
