title: Access method for distribution-sampled random numbers generation in Numpy
body: <p>I am interested in knowing which method Numpy uses in <code>numpy.random</code> to generate random numbers distributed as beta, lognormal, Weibull distributions, among others. <a href="https://numpy.org/doc/stable/reference/random/generator.html" rel="nofollow noreferrer">In the documentation</a> they often discuss the shape of the distribution, but how can I access to the method? For example, in <code>numpy.random.chisquare()</code> <a href="https://numpy.org/doc/stable/reference/random/generated/numpy.random.Generator.chisquare.html#numpy.random.Generator.chisquare" rel="nofollow noreferrer">the method is expained</a>, but not in others.</p>
