Eikos changelog

August 25, 2026

Engines now reach the interface: census analysis, spatial regression, difference-in-differences, interrupted time series, synthetic controls, hierarchical models, record linkage and risk scores now have visible product workflows.
Operational refusals: all 18 safeguards that stop unsupported calculations now have a real entry point; no refusal is inert and no public function remains without both a route and a test.
Survival and clinical data: Gray's test for competing risks, ICD-10 indexes and DOCX export are verified local capabilities rather than external blockers.
Accessible figures: JavaScript-generated colour ramps are tested against their real dark-mode surface and under colour-vision simulations.
Signed and notarised desktop build: the macOS build is signed with a Developer ID and passes Apple's notary service; Gatekeeper accepts it. Public installers remain undistributed until the update channel is decided.
Real progress on large files: opening a table larger than memory reports its two passes —hashing and profiling— separately, instead of a single bar with an invented split.
Complete verification: 106 suites, 48,908 checks, 132 journeys across three browsers, 27 core and desktop tests, and 569 site URLs before publishing.

Causal and population inference: new workflows for regression discontinuity, doubly robust methods, complex surveys, census data and stepped-wedge designs.
Defensible formatting: tables, numbers, intervals and exports are independently checked against R and Python.
Reproducible research: notebooks, reports and DOCX files retain methods, decisions and replication code.

Public library: each page contains an introduction and a LaTeX-rendered mathematical sample; full content remains inside Eikos.
Instrumental variables: causal diagrams lead into 2SLS, first-stage strength and Anderson–Rubin inference.
Missing data: patterns, complete-case cost, multiple imputation, Rubin pooling and declared-δ MNAR sensitivity.
529 guides and 2682 exercises: counted from the live corpus.

Preview under validation. Public installers are not available yet.
