From ec64eb401dc86d60f1028ec8db907eb7e0e64c4a Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 8 Sep 2026 09:48:19 +0000 Subject: [PATCH] Give EquityStack a page: the third site was missing Two of the three stack repositories had a designed landing page and this one had nothing, so the family read as two sites rather than three. GitHub Pages was already serving this repository; there was simply no index.html for it to serve. Built on the shared house style, leading with survey_estimation, which is the part of this repository worth reading first and the reason the rest exists: an independence standard error on a stratified, clustered sample is too small, often by a factor of two, and every interval built on it errs in the direction that flatters the result. Twelve module rows, each with a visible one-line description and each linking to GitHub, because they are Python modules to clone and run rather than pages to browse. No test or CI counts in the hero: a reader does not care how many checks run. _layouts/default.html and _config.yml render any folder README in the same style, so a click-through does not land somewhere that looks unrelated. Verified against a local Jekyll build: no broken internal links.

Survey estimation

The part worth reading first

+

Design-based standard errors

+

Weights are the easy half. A national household survey is stratified and clustered, so an + independence standard error is too small, often by a factor of two, and every interval + built on it errs in the direction that flatters the result. This implements Taylor + linearisation, the estimator behind Stata's svy: and R's survey.

Worked example

+

NFHS-5 stunting, reproduced

+

Rebuilds India's published stunting table by wealth quintile from the raw DHS children's + recode: 35.5 percent nationally, 46.1 in the poorest quintile falling to 22.9 in the + richest. Reproducing a published table is the only cheap proof a pipeline is right end + to end.

+

Read the script →

+ +
+

Checked against R's survey package on the same data, agreeing to + twelve significant figures. Three behaviours that look like details and are not: subgroups + are domains rather than subsets, proportions get a logit interval so a small one cannot go + negative, and intervals use t on clusters minus strata and say which distribution produced + them.

Status

+

Stable

+
+

This repository works and is correct, but is not under active development. Bug + reports are welcome and issues stay open; new features are unlikely, and replies are measured + in weeks rather than days. Dependencies are pinned deliberately so that a clone still runs + years from now. See the + maintenance policy.

+

The companion repositories are + InsightStack, which holds the calculators + and the loaders that produce the data this reads, and + FieldStack, which does the same work in R.
