[New tool] - Automated threshold detection for anomalies #524
Description
Tool description
This tool would allow for automated threshold detection when running distance to anomalies calculation, instead of having to rely on manual, user-based statistical analysis to set this threshold. This tool would rely on more advanced automated statistical analysis for threshold detection, with a list of predefined approaches that are more or less conservative, and more or less reliable depending on the dataset distribution (e.g., 75-85-95% cumulative frequency, bimodal population analysis,...).
Justification and importance
It would be great to guide the user with threshold definition, as this may be very arbitrary and strongly impacts further modeling. Not an essential tool, but almost!
Tool category and type
raster_processing
Implementation details
The tool takes raster or vector data as input (one band or one integer or float field to specify) and outputs a decimal number as a float.
I am pretty confident this functionality is already available in existing libraries, and can be easily replicated, but I do not know for a fact.
Who will implement the tool?
I hope someone will be happy to do it, and I am happy on my side to act as a beta tester :)
