Frequency components in a periodic 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’.

a_max : int, optional

The maximum scale / level (can be ‘max’ to set according to wmaxlev)

delta : int, optional

The sampling period.

Returns:

Dictionary containing the level with the highest energy coefficients, the dominant period, and the dominant pseudo-frequency.

Return type:
