Struct TabularData 

pub struct TabularData { /* private fields */ }

Tabular IID dataset.

Implementations

impl TabularData

pub fn new(storage: OwnedColumnarStorage) -> Self

Wrap owned storage.

pub fn from_f64_columns<'a, S>( columns: impl IntoIterator<Item = (S, &'a [f64])>, ) -> Result<Self, DataError>

where S: Into<Arc<str>>,

Build continuous f64 columns from named slices (equal length).

Schema variables are continuous with empty role hints, in iterator order. Dense VariableIds align with column order (0..n).

Errors

Empty input, length mismatch across columns, or schema construction failure.

pub fn try_from_schema_f64<'a>( schema: CausalSchema, columns: impl IntoIterator<Item = (&'a str, &'a [f64])>, ) -> Result<Self, DataError>

Bind named f64 slices to an existing schema (names must match; order may differ).

Errors

Missing/extra names, length mismatch, or storage construction failure.

pub fn storage(&self) -> &OwnedColumnarStorage

Borrow underlying storage.

impl TabularData

pub fn project(&self, ids: &[VariableId]) -> Result<(Self, IdRemap), DataError>

Project onto ids (order preserved, duplicates dropped).

Column value buffers are Arc-shared when possible; schema and column ids are rebuilt as contiguous 0..k-1. Analysis mask and weights are retained.

Errors

Unknown variable, empty selection, or schema construction failure.

impl TabularData

pub fn complete_case_mask( &self, ids: &[VariableId], ) -> Result<Vec<bool>, DataError>

Row mask: analysis mask ∩ validity of every listed column.

Errors

Unknown variables, or no remaining complete cases.

pub fn float64_masked( &self, id: VariableId, keep: &[bool], ) -> Result<Vec<f64>, DataError>

Extract float64 values for rows where keep[i] is true.

Errors

Unknown / non-float64 column, or keep length mismatch.

pub fn with_replaced_float( &self, id: VariableId, values: Arc<[f64]>, ) -> Result<Self, DataError>

Replace one float64 column; preserve other columns, analysis mask, and weights.

The replacement column is marked all-valid (caller supplies a complete vector).

Errors

Unknown id, length mismatch, or non-float target.

pub fn with_analysis_mask( &self, mask: ValidityBitmap, ) -> Result<Self, DataError>

Restrict analysis to rows where mask is valid, intersected (AND) with any existing analysis mask; preserves columns, validity, and weights.

Errors

Mask length mismatch.

pub fn with_appended_float( &self, name: &str, values: Arc<[f64]>, ) -> Result<(Self, VariableId), DataError>

Append a continuous float64 covariate; preserve existing columns/mask/weights.

Errors

Length mismatch or schema construction failure.
