Exploratory data analysis, data quality, and statistical diagnostics for the anofox_forecast DuckDB extension — 36 per-series statistics, data-quality scoring, quality-report summaries, 117 tsfresh-inspired feature extraction, and 7 diagnostic functions covering stationarity (ADF, KPSS, combined verdict) and residual adequacy (Ljung-Box, Durbin-Watson, Jarque-Bera, combined report). Use before forecasting to understand series characteristics (length, gaps, trend, seasonality strength…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Anofox Forecast — EDA & Data Quality Cheat Sheet
**Extension:** `anofox_forecast` v2026.09.26 (Rust crate `anofox-forecast` v0.16.2) | **DuckDB:** v2.0.0 / v1.5.6 | **Dual naming:** `ts_*` and `anofox_fcst_ts_*`
Understand your data before modelling it: per-series statistics, data-quality scores, feature vectors for ML.
## Statistics
### `ts_stats` (table function) — 36 metrics per series
```sql
ts_stats(source VARCHAR, group_col COLUMN, date_col COLUMN, value_col COLUMN,
frequency VARCHAR, seasonal_period := 0) → TABLE
```
Returns 36 columns: `length`, `n_nulls`, `n_nan`, `n_zeros`, `n_positive`, `n_negative`, `n_unique_values`, `is_constant`, `n_zeros_start`, `n_zeros_end`, `plateau_size`, `plateau_size_nonzero`, `mean`, `median`, `std_dev`, `variance`, `min`, `max`, `range`, `sum`, `skewness`, `kurtosis`, `tail_index`, `bimodality_coef`, `trimmed_mean`, `coef_variation`, `q1`, `q3`, `iqr`, `autocorr_lag1`, `trend_strength`, `seasonality_strength`, `entropy`, `stability`, plus date-derived `expected_length`, `n_gaps`, and `n_gap_runs`.
**v2026.10.16:** `skewness`/`kurtosis` are now textbook scipy `bias=False` G1/

How to install
mdr add datazoode/anofox-forecast/anofox-forecast-eda@sha256:4881da6cbdf5d022The line at the top of this page pins the label v2026.09.26, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
