Elastic Functional Principal Component Regression
J. Derek Tucker, John Lewis, Anuj Srivastava
We study regression using functional predictors in situations where these functions contain both phase and amplitude variability. In other words, the functions are misaligned due t…
Trend and Variable-Phase Seasonality Estimation from Functional Data
Liang-Hsuan Tai, Anuj Srivastava, Kyle A. Gallivan
The problem of estimating trend and seasonal variation in time-series data has been studied over several decades, although mostly using single time series. This paper studies the p…
Statistical analysis of trajectories on Riemannian manifolds: Bird migration, hurricane tracking and video surveillance
Jingyong Su, Sebastian Kurtek, Eric Klassen +1
We consider the statistical analysis of trajectories on Riemannian manifolds that are observed under arbitrary temporal evolutions. Past methods rely on cross-sectional analysis, w…
