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 ...

People and Nature, EarlyView.Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Modeling the Elastic Recovery of PET Bottles via a Free‐Blowing of Preforms Campaign
Polymer Engineering &Science, EarlyView.From free‐blown preforms to mechanical properties. ABSTRACT This study aims to quantify the elastic properties induced by biaxial stretching at different temperatures in order to simulate the complete process including the final elastic recovery. The elastic modulus is identified from geometric measurements obtained during free‐blowing experiments. PET
