Compositional Data Analysis research. Entropy-Invariant Time Transformer (EITT): Shannon entropy near-invariant under geometric-mean decimation. Validated on energy, chemistry (500k pts), hardware, climate. CoDaWork 2026. Not a game engine.

Higgins Decomposition (Hs) — deterministic compositional inference instrument. 18 domains, 36 systems. CNT engine + CNQ quaternion verification (IEEE-floor on Backblaze, Planck CMB, SM Neutrino). Apache-2.0 (code) + CC BY 4.0 (docs).

End-to-End Python implementation of a bankruptcy prediction method which adapts Altman's Z-Score to Compositional Data Analysis (Keivani et al., 2026). Benefits: Uses the Aitchison simplex to eliminate outliers & asymmetry in financial ratios. Pipeline: log-ratio EM imputation, pairwise log-ratios, ML classifiers (Logit/k-NN/RF), validation.
