This article motivates and discusses JosE Bernardo's attempt to reconcile the subjective Bayesian framework with a need for objective scientific inference, leading to a special kind of objective Bayesianism, namely reference Bayesianism. We elucidate principal ideas and foundational implications...

Due to their indeterminacies, static and dynamic factor models require identifying assumptions to guarantee uniqueness of the parameter estimates. The indeterminacy of the parameter estimates with respect to orthogonal transformations is known as the rotation problem. The typical strategy in...

Due to their well-known indeterminacies, factor models require identifying assumptions to guarantee unique parameter estimates. For Bayesian estimation, these identifying assumptions are usually implemented by imposing constraints on certain model parameters. This strategy, however, may result...

Long run developments such as income growth and urban sprawl lead one to expect a continuous decline of thecontribution of non-motorised transport modes to the performance of transport systems. In terms of the totalnumber of trips, non-motorised transport modes have retained high shares,...

In this paper we investigate the properties of some common test for asymmetry. The tests are based on moments, order statistics and empirical characteristic functions (ecf) respectively. These tests have completely different origins, relies on different characterizations of symmetry and does...

Modular concepts and logistics centers are the basic instruments for improving resource utilization in European transport system. Efficacy of the system and integration of transport services are not as advanced as they could be. Europe needs efficient logistics of freight traffic together with...
