# Struct rand_distr::Pareto

source · `pub struct Pareto<F>{ /* private fields */ }`

## Expand description

The Pareto distribution `Pareto(xₘ, α)`

.

The Pareto distribution is a continuous probability distribution with
scale parameter `xₘ`

( or `k`

) and shape parameter `α`

.

## §Plot

The following plot shows the Pareto distribution with various values of
`xₘ`

and `α`

.
Note how the shape parameter `α`

corresponds to the height of the jump
in density at `x = xₘ`

, and to the rate of decay in the tail.

## §Example

```
use rand::prelude::*;
use rand_distr::Pareto;
let val: f64 = thread_rng().sample(Pareto::new(1., 2.).unwrap());
println!("{}", val);
```
