Struct PolyaGamma

Source

pub struct PolyaGamma { /* private fields */ }

Expand description

Sampler for the Pólya-Gamma PG(1, c) distribution.

Implementations§

Source §

impl PolyaGamma

Source

pub fn new() -> Self

Construct a stateless Pólya–Gamma sampler. The struct caches the Exp(1) and N(0,1) distribution objects used by every Devroye rejection draw; the caller supplies the per-draw RNG via the draw(...) entry point, so a single PolyaGamma instance is safely reused across threads and chains.

Source

pub fn draw<R: Rng + ?Sized>(&self, rng: &mut R, tilt: f64) -> f64

Draw a single PG(1, c) variate using Devroye’s exact algorithm.
