scipy.stats.sampling.FastGeneratorInversion.
rvs#
- FastGeneratorInversion.rvs(size=None)[source]#
- Sample from the distribution by inversion. - Parameters:
- sizeint or tuple, optional
- The shape of samples. Default is - Nonein which case a scalar sample is returned.
 
- Returns:
- rvsarray_like
- A NumPy array of random variates. 
 
 - Notes - Random variates are generated by numerical inversion of the CDF, i.e., - ppfcomputed by- NumericalInversePolynomialwhen the class is instantiated. Note that the default- rvsmethod of the rv_continuous class is overwritten. Hence, a different stream of random numbers is generated even if the same seed is used.
