Expand description

Prior probability distribution for a probabilistic variable.

Variants§

§

Normal

Gaussian: N(mean, std²).

Fields

§mean: f64

§std: f64

§

Uniform

Continuous uniform on [low, high].

Fields

§low: f64

§high: f64

§

Beta

Beta distribution parameterised by α and β (support [0,1]).

Fields

§alpha: f64

§beta: f64

§

Exponential

Exponential distribution with given rate λ (support [0,∞)).

Fields

§rate: f64

§
