pyhctsa.operations.wavelet.detail_coeffs(y, w_name='db3', max_level=20)¶

Detail coefficients of a wavelet decomposition.

Compares the detail coefficients obtained at each level of the wavelet decomposition from 1 to the maximum possible level for the wavelet, given the length of the input time series.

Parameters:¶

y : array-like¶

The input time series.

w_name : str, optional¶

The name of the mother wavelet to analyze the data with (e.g., ‘db3’, ‘sym2’). See the Wavelet Toolbox or PyWavelets documentation for details. Default is ‘db3’.

max_level : int or 'max', optional¶

The maximum wavelet decomposition level. If ‘max’, uses the maximum allowed level for the data length and wavelet. Default is 20.

Returns:¶

Statistics on the detail coefficients at each level.

Return type:¶
