Struct KdeDoSampler 

pub struct KdeDoSampler {
    pub outcome: VariableId,
    pub bandwidth: Option<f64>,
}

KDE do-sampler: sample from interventional SCM then smooth the outcome with a Gaussian KDE.

Fields

outcome: VariableId

Outcome variable.

bandwidth: Option<f64>

Bandwidth (Silverman’s (1986) rule if None).

Implementations

impl KdeDoSampler

pub fn new(outcome: VariableId) -> Self

Construct.

pub fn sample( &self, model: &CompiledCausalModel, interventions: &[Intervention], n_draws: usize, rng: &mut CausalRng, ws: &mut MechanismWorkspace, ctx: &ExecutionContext, ) -> Result<DoSampleResult, ModelError>

Draw interventional samples and return KDE-ready values (+ bandwidth note).

Errors

Sampling failures.

pub fn density(result: &DoSampleResult, x: f64) -> f64

Evaluate KDE density at x given sampler values.

Trait Implementations

impl Clone for KdeDoSampler

fn clone(&self) -> KdeDoSampler

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

Performs copy-assignment from source.

impl Debug for KdeDoSampler

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