Peaks over threshold
WebSep 25, 2024 · Hi, I have a dataset with values with a time step of 3h. I need to find the values over a threshold i.e 7. When the value goes over 7 for some time and then down the threshold again counts as 1 event. I would like to count the number of events over that threshold for the whole data set.

WebExtreme Value Theory for Time Series using Peak-Over-Threshold method - Gianluca Rosso (2015) 4 Brief conclusions. The POT method assumes that once we have placed a threshold, all the items over this level are peaks. But as I wrote in a paper about the clustering (Rosso, 2014, Outliers Emphasis on Cluster Analysis - The use of squared Web2 Peaks-Over-Threshold The Peak Over Threshold-method (POT-method) is one way to model extreme values.

The first method relies on deriving block maxima (minima) series as a preliminary step. In many situations it is customary and convenient to extract the annual maxima (minima), generating an "Annual Maxima Series" (AMS).
