obspy.realtime.signal.kurtosis

kurtosis(trace, win=3.0, rtmemory_list=None)

Apply recursive kurtosis calculation on data.

Recursive kurtosis is computed using the [ChassandeMottin2002] formulation adjusted to give the kurtosis of a Gaussian distribution = 0.0.

Parameters:

• trace (Trace) – Trace object to append to this RtTrace

• win (float, optional) – window length in seconds for the kurtosis (default is 3.0 s)

• rtmemory_list (list of RtMemory, optional) – Persistent memory used by this process for specified trace

Return type:

NumPy numpy.ndarray

Returns:

Processed trace data from appended Trace object
