Struct EmpiricalTableProvider 

pub struct EmpiricalTableProvider { /* private fields */ }

Tabular empirical distribution provider (discrete factors + domains).

Implementations

impl EmpiricalTableProvider

pub fn new() -> Self

Empty provider.

pub fn set_domain( &mut self, var: VariableId, values: impl IntoIterator<Item = Value>, )

Declare discrete domain for a variable.

pub fn insert_probability( &mut self, spec: &FactorSpec<'_>, assignment: &Assignment, probability: f64, ) -> Result<(), EvalError>

Insert a factor probability for the given spec + assignment.

Errors

Missing bindings for factor variables / conditions.

Trait Implementations

impl Clone for EmpiricalTableProvider

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EmpiricalTableProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EmpiricalTableProvider

fn default() -> EmpiricalTableProvider

Returns the “default value” for a type.

impl DistributionProvider for EmpiricalTableProvider

fn probability( &self, spec: &FactorSpec<'_>, assignment: &Assignment, _ctx: &EvalContext, ) -> Result<f64, EvalError>

Probability / density mass for a factor under an assignment.

fn support( &self, vars: &[VariableId], _ctx: &EvalContext, ) -> Result<Arc<[Arc<[Value]>]>, EvalError>

Discrete support for variables (cartesian rows of values aligned to vars).

fn outcome( &self, var: VariableId, assignment: &Assignment, _ctx: &EvalContext, ) -> Result<f64, EvalError>

Outcome function value (identity: the bound value of var).

fn n_draws(&self) -> Option<usize>

Number of posterior draws, or None for a single empirical world.

fn quadrature( &self, _vars: &[VariableId], _ctx: &EvalContext, ) -> Result<Option<QuadratureNodes>, EvalError>

Optional continuous quadrature nodes (assignment_row, Lebesgue weight) for crate::ExprNode::IntegralOut.
