Struct DataSubsetRefuter 

pub struct DataSubsetRefuter {
    pub replicates: u32,
    pub subset_fraction: f64,
    pub alpha: f64,
    pub estimator: LinearAdjustmentAte,
}

Randomly subset rows and re-estimate; expect the ATE to move little.

Fields

replicates: u32

Replicate count (fresh subset draw per replicate).

subset_fraction: f64

Fraction of rows kept per replicate.

alpha: f64

Pass if the subset ATE distribution is consistent with the original estimate at this significance level (two-sided normal test on the replicates, p >= alpha).

estimator: LinearAdjustmentAte

Estimator used for refits (bootstrap disabled).

Implementations

impl DataSubsetRefuter

pub fn new() -> Self

Defaults: 20 replicates, 80% subset fraction, significance level 0.05.

pub fn refute( &self, problem: &RefutationProblem<'_>, workspace: &mut EstimationWorkspace, ctx: &ExecutionContext, ) -> Result<RefutationReport, ValidationError>

Run the data-subset refuter.

Errors

Data or estimation failures.
