DOI: 10.1080/10618600.2024.2365728
Abstract: Abstract Markov chain Monte Carlo (MCMC) allows one to generate dependent replicates from a posterior distribution for effectively any Bayesian hierarchical model. However, MCMC can produce a significant computational burden. This motivates us to consider… read more here.

DOI: 10.1111/ene.14993
Abstract: Cerebral amyloid angiopathy (CAA) is a well‐recognized contributor to cognitive decline in the elderly. The posterior cortical predilection of CAA pathology would cause visuospatial dysfunction, which is still underexplored. We aimed to investigate whether the… read more here.

DOI: 10.1214/22-sts868
Abstract: Gaussian process (GP) regression is computationally expensive in spatial applications involving massive data. Various methods address this limitation, including a small number of Bayesian methods based on distributed computations (or the divide-and-conquer strategy). Focusing on… read more here.
