Measuring precise radial velocities and cross-correlation function line-profile variations using a Skew Normal density
Umberto Simola, Xavier Dumusque, Jessi Cisewski-Kehe
Stellar activity is one of the primary limitations to the detection of low-mass exoplanets using the radial-velocity (RV) technique. We propose to estimate the variations in shape…
Finding cosmic voids and filament loops using topological data analysis
Xin Xu, Jessi Cisewski-Kehe, Sheridan B. Green +1
(abridged) We present the Significant Cosmic Holes in Universe (SCHU) method for identifying cosmic voids and loops of filaments in cosmological datasets and assigning their statis…
Statistical challenges in the search for dark matter
Sara Algeri, Melissa van Beekveld, Nassim Bozorgnia +19
The search for the particle nature of dark matter has given rise to a number of experimental, theoretical and statistical challenges. Here, we report on a number of these statistic…
Functional Summaries of Persistence Diagrams
Eric Berry, Yen-Chi Chen, Jessi Cisewski-Kehe +1
One of the primary areas of interest in applied algebraic topology is persistent homology, and, more specifically, the persistence diagram. Persistence diagrams have also become ob…
Approximate Bayesian Computation for Finite Mixture Models
Umberto Simola, Jessi Cisewski-Kehe, Robert L. Wolpert
Finite mixture models are used in statistics and other disciplines, but inference for mixture models is challenging due, in part, to the multimodality of the likelihood function an…
