Generate random samples from a probability density function using the
|

ratio-of-uniforms method.

|

.. deprecated:: 1.12.0
|
||||
`rvs_ratio_uniforms` is deprecated in favour of
|
||||
`scipy.stats.sampling.RatioUniforms` from version 1.12.0 and will
|
||||
be removed in SciPy 1.15.0
|
||||
|
||||
Parameters
|
||||
----------
|
||||
pdf : callable
|
||||
A function with signature `pdf(x)` that is proportional to the
|
||||
probability density function of the distribution.
|
||||
umax : float
|
||||
The upper bound of the bounding rectangle in the u-direction.
|
||||
vmin : float
|
||||
The lower bound of the bounding rectangle in the v-direction.
|
||||
vmax : float
|
||||
The upper bound of the bounding rectangle in the v-direction.
|
||||
size : int or tuple of ints, optional
|
||||
Defining number of random variates (default is 1).
|
||||
c : float, optional.
|
||||
Shift parameter of ratio-of-uniforms method, see Notes. Default is 0.
|
||||
random_state : {None, int, `numpy.random.Generator`,
|
||||
`numpy.random.RandomState`}, optional
|
||||
|
||||
If `seed` is None (or `np.random`), the `numpy.random.RandomState`
|
||||
singleton is used.
|
||||
If `seed` is an int, a new ``RandomState`` instance is used,
|
||||
seeded with `seed`.
|
||||
If `seed` is already a ``Generator`` or ``RandomState`` instance then
|
||||
that instance is used.
|
||||
|
||||
Returns
|
||||
-------
|
||||
rvs : ndarray
|
||||
The random variates distributed according to the probability
|
||||
distribution defined by the pdf.
|
||||
|
||||

|
||||
-----
|
||||
Please refer to `scipy.stats.sampling.RatioUniforms` for the documentation.
