greeners-core

Foundational data structures, utilities and numerical building blocks for the Greeners econometrics workspace.

Scope

• Data structures: DataFrame, Column, DataType, Formula.
• Linear algebra helpers: LinalgInverse, LinalgSVD, LinalgQR, etc.
• Statistical utilities: Stats, DescrStatsW, MultipleTests, ProportionTests, Bootstrap.
• Distributions: chi2_pvalue, t_pvalue_two, norm_pdf, etc.
• Multivariate methods: PCA, MANOVA, FactorAnalysis, CanCorr.
• Non-parametric tools: KDEUnivariate, KernelReg, Lowess.
• I/O and predicates: Datasets, RowPredicate.
• Common error type: GreenersError.

Usage

[dependencies]
greeners-core = "2.0"

use greeners_core::{DataFrame, Formula, Stats};

let df = DataFrame::from_columns(vec![
    ("y".to_string(), vec![1.0, 2.0, 3.0]),
    ("x".to_string(), vec![1.0, 2.0, 3.0]),
]).unwrap();

let formula = Formula::parse("y ~ x").unwrap();
let stats = Stats::new(&df);

Design notes

• Items with unique names within the crate are re-exported at the crate root.
• Items whose names appear in more than one module remain namespaced under greeners_core::<module>.
• This crate is the foundation of the workspace: all other Greeners crates depend on it.
