TitleClassification and clustering of time series with data-driven fragmented statistics (cont.)
ParticipantsJorge Caiado (Principal Investigator), Nuno Crato
SummaryThis research aims to advance methodologies for classifying and clustering time series in
challenging scenarios characterized by noisy data and unknown structures. Specifically, the study
introduces innovative discrepancy metrics that leverage significant autocorrelations and partial
autocorrelations to calculate distances between time series. Through an extensive simulation study
involving diverse linear, stationary, near nonstationary, and nonstationary models, the performance
and robustness of the proposed metrics are evaluated. The study also explores the practical
applicability of these methods in capturing meaningful patterns in real-world data, particularly in
economic and financial time series. By addressing limitations of existing approaches, this project
contributes to the development of robust, data-driven tools for analyzing complex time series
datasets.
