I want to make sure how
sfxDQFindOutliers works. I am trying to use this function for a signal that has several outliers with values such as 1e15 (while normal values are less than 1e4). I do not get results from
sfxDQFindOutliers that I would expect.
I see that
sfxDQJob computes statistics that are added to each point as
1, These statistics are computed on interval that is given by parametr
dateRange. It means that for example
hisDQAverage is average over last year?
2, Outliers are detected
if (value < hisDQAverage - sDs*standard_deviation) or (value > hisDQAverage + sDs*standard_deviation)?
3, How are
NA values handled? Do I have to remove these values before
