Brian Nord, Andrew J. Connolly, Jamie Kinney +35
The field of astronomy has arrived at a turning point in terms of size and complexity of both datasets and scientific collaboration. Commensurately, algorithms and statistical mode…
A statistical framework for measuring the temporal stability of human mobility patterns
Zhihang Dong, Yen-Chi Chen, Adrian Dobra
Despite the growing popularity of human mobility studies that collect GPS location data, the problem of determining the minimum required length of GPS monitoring has not been addre…
Nonparametric Pattern-Mixture Models for Inference with Missing Data
Yen-Chi Chen, Mauricio Sadinle
Pattern-mixture models provide a transparent approach for handling missing data, where the full-data distribution is factorized in a way that explicitly shows the parts that can be…
Alignment between filaments and galaxy spins from the MaNGA integral-field survey
Alex Krolewski, Shirley Ho, Yen-Chi Chen +4
Halos and galaxies acquire their angular momentum during the collapse of surrounding large-scale structure. This process imprints alignments between galaxy spins and nearby filamen…
