SCONCE: A cosmic web finder for spherical and conic geometries
Yikun Zhang, Rafael S. de Souza, Yen-Chi Chen
The latticework structure known as the cosmic web provides a valuable insight into the assembly history of large-scale structures. Despite the variety of methods to identify the co…
Handling Nonmonotone Missing Data with Available Complete-Case Missing Value Assumption
Gang Cheng, Yen-Chi Chen, Maureen A. Smith +1
Nonmonotone missing data is a common problem in scientific studies. The conventional ignorability and missing-at-random (MAR) conditions are unlikely to hold for nonmonotone missin…
Long-term effect estimation when combining clinical trial and observational follow-up datasets
Gang Cheng, Yen-Chi Chen, Joseph M. Unger +2
Combining experimental and observational follow-up datasets has received much attention lately. In a survival setting, recent work has used Medicare claims to extend the follow-up…
Efficient Community Detection in Large-Scale Dynamic Networks Using Topological Data Analysis
Wei Guo, Ruqian Chen, Yen-Chi Chen +1
In this paper, we propose a method that extends the persistence-based topological data analysis (TDA) that is typically used for characterizing shapes to general networks. We intro…
The emptiness inside: Finding gaps, valleys, and lacunae with geometric data analysis
Gabriella Contardo, David W. Hogg, Jason A. S. Hunt +2
Discoveries of gaps in data have been important in astrophysics. For example, there are kinematic gaps opened by resonances in dynamical systems, or exoplanets of a certain radius…
