Documentation

README

Excerpt

Rylai Analytics Implementation

Build analysis that another person can rerun and audit.

Define The Contrac

Capture the following before choosing methods:

decision or question the analysis must support;
input files, tables, date range, units, and grain;
metric definitions and inclusion rules;
expected deliverable: script, notebook, chart set, table, or report;
runtime limits, privacy constraints, and required output path.

Inspect the real input before assuming its schema.

Implementation Workflow

Inventory
- Record source names, sizes, columns, types, row counts, and keys.
- Detect encoding, delimiter, duplicate-key, timezone, and locale issues.

This is the opening of the README. Read the full README on GitHub.
