Bayesian Changepoint Estimation for Spatially Indexed Functional Time Series
Mengchen Wang, Trevor Harris, Bo Li
We propose a Bayesian hierarchical model to simultaneously estimate mean based changepoints in spatially correlated functional time series. Unlike previous methods that assume a sh…

Evaluating proxy influence in assimilated paleoclimate reconstructions -- Testing the exchangeability of two ensembles of spatial processes
Trevor Harris, Bo Li, Nathan Steiger +3
Climate field reconstructions (CFR) attempt to estimate spatiotemporal fields of climate variables in the past using climate proxies such as tree rings, ice cores, and corals. Data…

Elastic depths for detecting shape anomalies in functional data
Trevor Harris, James Derek Tucker, Bo Li +1
We propose a new family of depth measures called the elastic depths that can be used to greatly improve shape anomaly detection in functional data. Shape anomalies are functions th…
