WebDefinitionThe Peaks Over Threshold (POT) series contains all peak flows that are greater than a given threshold flow, the threshold is generally set to include an average of 5 events per year. Where multiple peak flows occur in a single event, the largest is used for the POT series (See FEH Volume 3, section 23.5.1).Data SourcesThe source of each POT value is … WebNov 27, 2024 · A python package for Extreme Value Analysis. generalized-pareto-distribution block-maxima extreme-value-analysis peaks-over-threshold generalized-extreme-value Updated on Apr 18, 2024 Jupyter Notebook calvinnsmith / Financial-Risk Star 0 Code Issues Pull requests Repository for the course 'Financial Risk' at Gothenburg University

Use findpeaks from the Octave-Forge signal package through the oct2py bridge. This algorithm allows to make a double sided detection, which means it will detect both local maxima and minima in a single run. Requires a rather complicated and not very efficient setup to be called from Python code. trier family chiropractic
