(X, sfreq, mode=’multitaper’, fmin=0, fmax=inf, fsum=True, n_fft=None, mt_bandwidth=None, mt_adaptive=False, mt_low_bias=True, verbose=None)[source]¶Estimate crossspectral density from an array.
Note
Results are scaled by sampling frequency for compatibility with Matlab.
Parameters:  X : arraylike, shape (n_replicates, n_series, n_times)
sfreq : float
mode : str
fmin : float
fmax : float
fsum : bool
n_fft : int  None
mt_bandwidth : float  None
mt_adaptive : bool
mt_low_bias : bool
verbose : bool, str, int, or None


Returns:  csd : array, shape (n_freqs, n_series, n_series) if fsum is True, otherwise (n_series, n_series).
freqs : array
