Struct McmcConfig 

pub struct McmcConfig {
    pub n_samples: usize,
    pub n_warmup: usize,
    pub thin: usize,
    pub seed: u64,
    pub target_acceptance: f64,
}

Configuration shared by all MCMC samplers.

Fields

n_samples: usize

Number of post-warmup samples to collect (default: 1000).

n_warmup: usize

Number of burn-in steps to discard (default: 500).

thin: usize

Thinning factor: keep every thin-th sample (default: 1).

seed: u64

RNG seed for reproducibility (default: 42).

target_acceptance: f64

Target acceptance rate for adaptive step-size tuning (default: 0.234 for MH).

Implementations

impl McmcConfig

pub fn new() -> Self

pub fn n_samples(self, n: usize) -> Self

Set the number of post-warmup samples.

pub fn n_warmup(self, n: usize) -> Self

Set the number of burn-in (warmup) steps.

pub fn thin(self, t: usize) -> Self

Set the thinning factor.

pub fn seed(self, s: u64) -> Self

Set the RNG seed.
