variance-decomposition

Insight & Inference for DVARS: 3-part variance decomposition, gives units & p-values to DVARS measures as well as spatiotemporal rs-fMRI diagnostic.

Model, Not Mode: a pre-registered comparison of fast and reasoning modes across six LLM families, using 60 chat-app answers to one constrained systems-design task, blind scoring and variance decomposition. Includes data, analysis code and reproducible results.

A diagnostic control paradigm for activation measurements in transformer language models. Cross-replay separates text-bound from architecture-bound components by replaying generated sequences through intact and perturbed model variants.

Deterministic engine for 'why did this metric change?' — decomposes the move over a hypothesis tree you define, reconciles every step, and abstains instead of guessing.

Code, configurations, per-run metadata, and pre-registered analysis for a 204-run study decomposing held-out loss variance in federated LoRA fine-tuning into partition-draw, interaction, and training-seed components (FedIT, FFA-LoRA, FLoRA; TinyLlama-1.1B, LLaMA-3.2-3B).

Global sensitivity analysis — Song 2016 Shapley effects, Rabitti-Tzougas 2025 CLH subsampling, exposure-weighted variance decomposition

Which timing unit do speakers reproduce? Cross-repetition variance decomposition of Persian read speech

Separating driver skill from car performance in Formula 1 using ridge regression on 25 years of race data (2000-2024).

Longitudinal three-level outcomes analysis with mixed-effects models, variance decomposition, diagnostics, and parallel R/Stata implementations.

End-to-End Python implementation of the Mesoscopic Structural Risk-Navigation System from Shao, Yang & Zhang (2026). Estimates rolling QVAR models, extracts multiscale network backbones via Disparity Filter, enumerates 13 directed triadic motifs (30 node orbits), and optimizes a Minimum Structural Similarity Portfolio.

Price and basket, more than foot traffic: what explains revenue differences across 27 brands at one Delhi market. Data, notebook, figures and a short note.
