Struct rand::distributions::gamma::ChiSquared [] [src]

pub struct ChiSquared { /* fields omitted */ }
🔬 This is a nightly-only experimental API. (rand)

use rand from crates.io

The chi-squared distribution χ²(k), where k is the degrees of freedom.

For k > 0 integral, this distribution is the sum of the squares of k independent standard normal random variables. For other k, this uses the equivalent characterization χ²(k) = Gamma(k/2, 2).

Methods

impl ChiSquared
[src]

🔬 This is a nightly-only experimental API. (rand)

use rand from crates.io
