Realizing the potential of astrostatistics and astroinformatics
Gwendolyn Eadie, Thomas J. Loredo, Ashish A. Mahabal +12
This Astro2020 State of the Profession Consideration White Paper highlights the growth of astrostatistics and astroinformatics in astronomy, identifies key issues hampering the mat…
Trend Filtering -- I. A Modern Statistical Tool for Time-Domain Astronomy and Astronomical Spectroscopy
Collin A. Politsch, Jessi Cisewski-Kehe, Rupert A. C. Croft +1
The problem of denoising a one-dimensional signal possessing varying degrees of smoothness is ubiquitous in time-domain astronomy and astronomical spectroscopy. For example, in the…
Adaptive Approximate Bayesian Computation Tolerance Selection
Umberto Simola, Jessica Cisewski-Kehe, Michael U. Gutmann +1
Approximate Bayesian Computation (ABC) methods are increasingly used for inference in situations in which the likelihood function is either computationally costly or intractable to…
A Preferential Attachment Model for the Stellar Initial Mass Function
Jessi Cisewski-Kehe, Grant Weller, Chad Schafer
Accurate specification of a likelihood function is becoming increasingly difficult in many inference problems in astronomy. As sample sizes resulting from astronomical surveys cont…
Modeling the Echelle Spectra Continuum with Alpha Shapes and Local Regression Fitting
Xin Xu, Jessi Cisewski-Kehe, Allen B. Davis +2
Continuum normalization of echelle spectra is an important data analysis step that is difficult to automate. Polynomial fitting requires a reasonably high order model to follow the…
Astro2020 Science White Paper: The Next Decade of Astroinformatics and Astrostatistics
A. Siemiginowska, G. Eadie, I. Czekala +49
Over the past century, major advances in astronomy and astrophysics have been largely driven by improvements in instrumentation and data collection. With the amassing of high quali…
