Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Public Sustainability: Thematic Mapping, Theoretical Approaches and Emerging Lines of Action

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The paucity of research analysing thematic persistence in public sustainability limits our understanding of how this field of research evolves and reconfigures itself. The present paper addresses this gap through a longitudinal bibliometric analysis of 692 publications processed with SciMAT. The methodology combines co‐word analysis, strategic
