%(after_notes)s
A common parameterization for expon is in terms of the rate parameter lambda, such that pdf = lambda * exp(-lambda * x). This parameterization corresponds to using scale = 1 / lambda.
The exponential distribution is a special case of the gamma distributions, with gamma shape parameter a = 1.
