- nigsp.operations.timeseries.demean_ts(timeseries, globally=False)[source]¶
Demean timeseries.
It is assumed that time is encoded in the second dimension (axis 1), e.g. for 90 voxels and 300 timepoints, shape is [90, 300].
- Parameters:
- timeseries
numpy.ndarray
The input timeseries. It is assumed that the second dimension is time.
- globally
bool
, optional If True, demean timeseries across the first two axes.
- timeseries
- Returns:
numpy.ndarray
The demeaned timeseries if timeseries is not a 1D array. If timeseries is a 1D array, it is returned as is.
