Struct rand::distributions::gamma::GammaSmallShape [−] [src]

struct GammaSmallShape {
    inv_shape: f64,
    large_shape: GammaLargeShape,
}

Unstable (rand)
: use rand from crates.io

Gamma distribution where the shape parameter is less than 1.

Note, samples from this require a compulsory floating-point pow call, which makes it significantly slower than sampling from a gamma distribution where the shape parameter is greater than or equal to 1.

See Gamma for sampling from a Gamma distribution with general shape parameters.
