Haybarn extension: stats_duck

A statistical computing toolkit for DuckDB — descriptive statistics, hypothesis tests, R-style distribution functions (d/p/q/r), OLS regression with HC and cluster-robust standard errors, grammar-of-graphics charts (VISUALIZE → Vega-Lite), and first-class readers/writers for SAS, SPSS, and Stata files, all directly in SQL.

Install

npm install @haybarn/ext-stats_duck-h1-5-5
# or use the exact version:
npm install @haybarn/[email protected]

npm picks the matching platform binary from the leaves below via its os / cpu / libc fields. No postinstall scripts, no network calls after npm install.

Available platforms (this version)

Installed automatically by npm install @haybarn/ext-stats_duck-h1-5-5 (npm picks the one matching your os/cpu/libc):

• @haybarn/ext-stats_duck-h1-5-5-darwin-x64
• @haybarn/ext-stats_duck-h1-5-5-darwin-arm64
• @haybarn/ext-stats_duck-h1-5-5-win32-x64
• @haybarn/ext-stats_duck-h1-5-5-linux-x64
• @haybarn/ext-stats_duck-h1-5-5-linux-arm64

WebAssembly (duckdb-wasm)

Also built for duckdb-wasm. These are not installed by the meta above (npm has no wasm os/cpu to match) — install the variant matching your duckdb-wasm bundle (mvp / eh / threads) and point duckdb-wasm at the bundled asset:

• @haybarn/ext-stats_duck-h1-5-5-wasm-eh
• @haybarn/ext-stats_duck-h1-5-5-wasm-threads
• @haybarn/ext-stats_duck-h1-5-5-wasm-mvp

npm install @haybarn/ext-stats_duck-h1-5-5-wasm-eh

import extUrl from '@haybarn/ext-stats_duck-h1-5-5-wasm-eh/bin/stats_duck.duckdb_extension.wasm?url';
await conn.query(`INSTALL stats_duck FROM '${extUrl}'`);
await conn.query(`LOAD stats_duck`);

Use it

Once installed, the .duckdb_extension binary lands in your project's node_modules/ tree under the matching leaf. The Haybarn engine auto-discovers it at startup; from a Haybarn SQL session:

LOAD stats_duck;
