Struct ChangeAttributionQuery 

pub struct ChangeAttributionQuery {
    pub outcome: VariableId,
    pub baseline: PopulationSelector,
    pub comparison: PopulationSelector,
    pub components: AttributionComponents,
    pub allocation: AllocationMethod,
    pub max_components: usize,
}

Distribution / population change attribution query.

Fields

outcome: VariableId

Outcome whose marginal (or summary) change is attributed.

baseline: PopulationSelector

Baseline population / period.

comparison: PopulationSelector

Comparison population / period.

components: AttributionComponents

Which structural pieces participate.

allocation: AllocationMethod

Allocation rule.

max_components: usize

Maximum number of attribution components (hard size guard for Exact).

Implementations

impl ChangeAttributionQuery

pub fn new( outcome: VariableId, baseline: PopulationSelector, comparison: PopulationSelector, ) -> Self

Construct with Shapley Monte Carlo allocation (common pinned baseline-GCM path).

pub const fn with_components(self, components: AttributionComponents) -> Self

Set component family.

pub fn with_allocation(self, allocation: AllocationMethod) -> Self

Set allocation method.

pub const fn with_max_components(self, max_components: usize) -> Self

Cap the number of components considered.

pub fn validate(&self) -> Result<(), QueryError>

Validate query.

Errors

Invalid populations, allocation, or zero max_components.
