Markov Chain Monte Carlo

Phylogenetic trees are key objects for understanding evolutionary history, first used to describe relationships between groups of species. Phylogenies help us to fill out the tree of life and to describe the dynamics that have given rise to the diversity of life on Earth. As we …

Traditional phylogenetic inference assumes that the history of a set of taxa can be explained by a tree. This assumption is often violated as some biological entities can exchange genetic material giving rise to non-treelike events often called reticulations. Failure to consider…

Phylogenetic trees play a central role in almost all of biology. These trees have emerged as a powerful paradigm in the post-genomic era to elucidate the processes that shaped the evolutionary history. Species trees model how species split and diversify from their most recent co…

In the paper, we propose a new methodology to test and date the financial contagion. The newly proposed multivariate model not only incorporates endogenous structural breaks but also encompasses a "mixed" version of state-space model. It provides a "direct" test for the presence…
