get_perturbation
(ts, axis=- 1)[source]¶ Compute the perturbation from the mean of a time series.
- Parameters
ts (array_like) – The time series from which you wish to find the perturbation time series (perturbation from the mean).
- Returns
array_like – The perturbation time series.
- Other Parameters
axis (int) – The index of the time axis. Default is -1
Notes
The perturbation time series produced by this function is defined as the perturbations about the mean:
x(t)′=x(t)−¯x(t)
