rvs(alpha: float, spectral_measure_sampler: BaseSpectralMeasureSampler | Literal['standard_isotropic_2d', 'standard_isotropic_3d', '1x2_elliptic_2d', '1x2x4_elliptic_3d', 'coin_flip_discrete'] = 'standard_isotropic_2d', shift: ndarray = 0, size: int | None = None, random_state: None | int | RandomState | Generator = None)

Sample from a multivariate alpha stable distribution.

Parameters

alphafloat

The alpha parameter of the alpha stable distribution.

spectral_measure_samplerBaseSpectralMeasureSampler or str

The spectral measure sampler to use.

shiftnp.ndarray

The shift vector to apply to the samples.

sizeint or tuple of ints, optional

Defines the shape of the returned array. Default is 1.

random_stateint or None, optional

Random state to use for the random number generator.

Returns
