Struct rand::distributions::gamma::ChiSquared
[−]
[src]
pub struct ChiSquared { /* fields omitted */ }Unstable (
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]
fn new(k: f64) -> ChiSquared
Unstable (
rand): use rand from crates.io
Create a new chi-squared distribution with degrees-of-freedom
k. Panics if k < 0.
