How proper are Bayesian models in the astronomical literature?
The well-known Bayes theorem assumes that a posterior distribution is a probability
distribution. However, the posterior distribution may no longer be a probability distribution if …

Leveraging single-case results to Bayesian hierarchical modelling
In scientific research, we often aim to learn one or more parameters of instances (objects)
from a population—such as the batting averages of a group of baseball players and …

Bayesian hierarchical modelling of initial–final mass relations acrossstar clusters
The initial–final mass relation (IFMR) of white dwarfs (WDs) plays an important role in stellar
evolution. To derive precise estimates of IFMRs and explore how they may vary among star …
