(since C++11) | |
Produces random positive integer values x, distributed according to probability density function:
- P(x|α,β) =
e-x/β βα · Γ(α)
where α is known as the shape parameter and β is known as the scale parameter.
For integer α, the value obtained is the sum of α independent exponentially distributed random variables, each of which has a mean of β
