所有分布都是 rv_continuous(连续型分布) 与 rv_discrete(离散型分布) 的实例

rv_continuous([momtype, a, b, xtol, ...]) A generic continuous random variable class meant for subclassing.

rv_discrete([a, b, name, badvalue, ...]) A generic discrete random variable class meant for subclassing.

rv_histogram(histogram, *args, **kwargs) Generates a distribution given by a histogram.
