[SciPy-User] handling outliers

[Предеин П. А.]

I have such question: what is the best way to remove outliers from
array (from timeseries, for example)? I consider using
scikits.timeseries library, and saw it's anom() function. But I have
mean and deviation values being changing drammatically in my serie
(like sin but also growing y-level).
Applying "mean()+/-3*std()" will cut some useful points and leave
outliers somewhere.
Please, help.
