eelbrain.powerlaw_noise(dims, exponent)¶

Gaussian $(1/f)^{exponent}$ noise.

Parameters:	dims : list of Dimension \| NDVar Shape of the noise. exponent : float The power-spectrum of the generated noise is proportional to $S(f) = (1 / f)^{exponent}$ flicker/pink noise: `exponent=1` brown noise: `exponent=2`
