Enum Dictionary 

pub enum Dictionary {
    Polynomial {
        degree: usize,
        treatment_degree: usize,
    },
    Custom(Arc<dyn Fn(ArrayView2<'_, f64>) -> Result<Array2<f64>> + Send + Sync>),
}

Basis functions b(w) in which the Riesz representer is approximated.

Variants

Polynomial

d^a · x^e for treatment powers a = 0, …, treatment_degree and all monomials x^e of the covariates up to total degree degree (including the constant).

Fields

degree: usize

treatment_degree: usize

Custom(Arc<dyn Fn(ArrayView2<'_, f64>) -> Result<Array2<f64>> + Send + Sync>)

Any basis: a closure from w (treatment in column 0) to the matrix of basis functions.

Implementations

impl Dictionary

pub fn custom( basis: impl Fn(ArrayView2<'_, f64>) -> Result<Array2<f64>> + Send + Sync + 'static, ) -> Self

pub fn apply(&self, w: ArrayView2<'_, f64>) -> Result<Array2<f64>>

The basis functions at the rows of w.

Trait Implementations

impl Clone for Dictionary

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for Dictionary

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

Formats the value using the given formatter.

impl Default for Dictionary

fn default() -> Self

Returns the “default value” for a type.
