I'm Siyang Li, a Ph.D. student deeply immersed in the statistical world (this is a pun), now focusing on astrostatistics. My journey into astrophysics is driven by a strong passion for developing new statistical tools to help astronomers make new discoveries. When I'm not exploring the universe through numbers, I enjoy football news, classical music, Arknights and books!

An alternative way to estimate the marginal likelihood for posterior samples.
This project explains and extends Bocharov and Harris (2014) by obtaining some corresponding mathematical results for a model where two points allow binary fission to occur.
Examples of marginal likelihood computation using the inflated density ratio approach and comparisons with other computation methods.
By applying rjmcmc in the computation of the number of principle components to be included in Bayesian models, the methodology of algorithm construction for Bayesian model selection based on rjmcmc for core-collapse supernovae gravitational wave data is investigated.
Numerical examples where differences between frequentist and Bayesian frameworks exist solidly, followed by a tool to magnify these differences.
