Documentation for some algorithms is wrong?

[mspiegel]

In https://github.com/etsy/skyline/blob/master/src/analyzer/algorithms.py in the documentation for functions stddev_from_average, stddev_from_moving_average, and mean_subtraction_cumulation the threshold is stated as one standard deviation. However in the implementations it looks like three standard deviations is the threshold. Am I missing something?

@mspiegel you are indeed correct - I've fixed up the docs there, it is indeed 3 stddev.
