If I understand your question correctly, then it's just a compatibility
interface. I'm not sure which part of the original algorithm you are
The random numbers are generated by the Mersenne Twister algorithm in
mtrand. Each generator in numpy.random.oldrng creates a new RandomState
for generation using that algorithm. The density function
calculations were taken from RNG, but the random-number generators
themselves are methods of the RandomState.
