Statistical Oceanography of Profiling Floats and Surface Drifters
Mikael Kuusela, Sofia C. Olhede, Adam M. Sykulski
The Global Ocean Observing System is key to understanding oceanic variability and climate change. The ocean is vast and often sparsely and irregularly sampled in time and space by…
nethist: An R package for Nonparametric Graphon Estimation via Network Histograms
Youngseok Song, Sofia C. Olhede
Understanding the generative mechanism of real-world networks is crucial for analyzing connection patterns and making inference from network data. Graphons are widely used to model…
Joint Estimation of Sparse Multilayer Networks via Graph Limits
Youngseok Song, Sofia C. Olhede
Network datasets in modern applications often involve multiple types of interactions occurring over a shared set of individuals. Characterizing the generating mechanisms of these i…
Decorated graphons for temporal network estimation
Charles Dufour, Sofia C. Olhede
We propose a unified nonparametric framework for modeling time-evolving networks using decorated graphons (also known as probability-graphons): symmetric functions that assign to e…
Irregularly and incompletely sampled random fields in the Earth sciences: Analysis and synthesis of parameterized covariance models
Olivia L. Walbert, Frederik J. Simons, Arthur P. Guillaumin +1
We study how sampling geometry contributes to uncertainty in modeling spatial geophysical observations as sampled random fields characterized by stationary, isotropic, parametric c…
Dependencies in Multiplex Networks: A Motif Count Approach
Karl Sawaya, Sofia Olhede
Multiplex networks are a powerful framework for representing systems with multiple types of interactions among a common set of entities. Understanding their structure requires stat…
