How proper are Bayesian models in the astronomical literature?
Hyungsuk Tak, Sujit K. Ghosh, Justin A. Ellis
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…
Robust and Accurate Inference via a Mixture of Gaussian and Student's t Errors
Hyungsuk Tak, Justin A. Ellis, Sujit K. Ghosh
A Gaussian measurement error assumption, i.e., an assumption that the data are observed up to Gaussian noise, can bias any parameter estimation in the presence of outliers. A heavy…
Disentangling Time Series Spectra with Gaussian Processes: Applications to Radial Velocity Analysis
Ian Czekala, Kaisey S. Mandel, Sean M. Andrews +4
Measurements of radial velocity variations from the spectroscopic monitoring of stars and their companions are essential for a broad swath of astrophysics, providing access to the…
