Workshop on Time Series Analysis
22-24 November, 2022
The University of Auckland, Grafton Campus
The workshop aimed at mathematicians, physiologists, engineers and scientists who are not expert in time-series analysis and provided theoretical background as well as hands-on experience.
We learned how to detect oscillations, discern determinism from seemingly noisy data and infer interactions and couplings between oscillatory processes.
Attendees had the opportunity to analyse their own signals. A toolbox MODA (Multiscale Oscillatory Dynamics Analysis, https://github.com/luphysics/MODA) was introduced and guidance on how to use it was provided.
Our invited speakers were Prof Aneta Stefanovska, Lancaster University, UK, Prof Peter McClintock, Lancaster University, UK, Associate Professor Jeffrey Hogan, the University of Newcastle, Australia, and Ms Juliane Bjerkan, Lancaster University, UK.
