Struct GammaDistribution

#[non_exhaustive]
pub struct GammaDistribution {
    pub shape: f64,
    pub rate: f64,
}

Represents a Gamma distribution

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

shape: f64

Shape parameter

rate: f64

Rate (inverse scale) parameter

Implementations

impl GammaDistribution

pub fn new(shape: f64, rate: f64) -> Result<GammaDistribution, RegressionError>

Constructs a new Gamma distribution from the provided parameters

Arguments

shape - The shape parameter rate - The rate parameter
