Struct Cvar 

pub struct Cvar { /* private fields */ }

Conditional value at risk of the potential outcome, E[Y(d) | Y(d) ≥ q_τ(Y(d))], as DoubleML’s DoubleMLCVAR. ml_g is a regressor, ml_m a classifier for P(D = 1 | X). The score is linear.

Implementations

impl Cvar

pub fn new( ml_g: impl Regressor + 'static, ml_m: impl Classifier + 'static, ) -> Self

pub fn from_boxed(ml_g: Box<dyn Regressor>, ml_m: Box<dyn Classifier>) -> Self

pub fn treatment(self, treatment: u8) -> Self

Treatment level d of the potential outcome (0 or 1, default 1).

pub fn quantile(self, quantile: f64) -> Self

Quantile level τ in (0, 1) (default 0.5).

pub fn clipping_threshold(self, t: f64) -> Self

Propensity scores are clipped to [t, 1 − t] (default t = 0.01).

pub fn normalize_ipw(self, normalize: bool) -> Self

Normalise the inverse-probability weights (default true, as DoubleML).

pub fn calibration(self, calibration: Calibration) -> Self

Calibrate the propensity scores before clipping (default: none), as DoubleML’s ps_processor_config.

pub fn n_folds(self, n_folds: usize) -> Self

Number of cross-fitting folds (default 5).

pub fn n_rep(self, n_rep: usize) -> Self

Number of independent sample splits (default 1). Estimates are aggregated across repetitions by the median, as in DoubleML.

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

Seed for the sample splits (default 0).

pub fn fit(&self, data: &DmlData) -> Result<DmlFit>

Draw seeded sample splits and fit. With clustered data (DmlData::with_clusters) whole clusters are assigned to folds and standard errors are cluster-robust.

pub fn fit_with_cluster_folds( &self, data: &DmlData, splits: &[Vec<ClusterFold>], ) -> Result<DmlFit>

Fit clustered data with explicit cluster folds, one Vec<ClusterFold> per repetition.

pub fn sensitivity_benchmark( &self, data: &DmlData, long: &DmlFit, benchmarking_set: &[usize], ) -> Result<SensitivityBenchmark>

Sensitivity benchmark for the covariate columns benchmarking_set: refits this model without them (with the same sample splitting, so long must come from fit with the current settings) and compares it with long.

pub fn fit_with_folds( &self, data: &DmlData, splits: &[Vec<Fold>], ) -> Result<DmlFit>

Fit with caller-supplied splits, one Vec<Fold> per repetition (e.g. to reproduce another implementation exactly).

Trait Implementations

impl LinearScoreModel for Cvar

fn name(&self) -> String

Label for summaries, e.g. "PLR (partialling out)".

fn validate(&self, data: &DmlData) -> Result<()>

Reject data the model cannot handle (called once before fitting).

fn strata(&self, data: &DmlData) -> Option<Vec<usize>>

Strata for the default sample splits (e.g. treatment levels), so each fold holds about the same share of every stratum. None (the default) draws plain K-fold splits.

fn estimate_score( &self, input: &ScoreInput<'_>, folds: &[Fold], ) -> Result<ScoreEstimate>

Cross-fit the nuisances on folds and return the score elements.
