macroforecast 0.9.3b1

Fair, reproducible macro forecasting benchmarking package

macroforecast

Fair, reproducible macro forecasting benchmarking. One YAML recipe → end-to-end study with bit-exact replication.

v0.9.3b1 — extensive test suite (counts vary by extras and Python version; see CI badges above).

Renamed from macrocast -> macroforecast in v0.6.0 (PyPI namespace ownership). See CHANGELOG.md for the migration diff.

Install

pip install macroforecast                    # core
pip install 'macroforecast[deep]'            # + torch / captum (LSTM / GRU / Transformer)
pip install 'macroforecast[xgboost,lightgbm]'  # + optional gradient-boosting backends
pip install 'macroforecast[tuning]'          # + optuna for bayesian_optimization
pip install 'macroforecast[shap]'            # + shap package for richer L7 figures

Or pin to a tagged release directly from GitHub:

pip install "git+https://github.com/NanyeonK/macroforecast.git@v0.9.3b1"

For development:

git clone https://github.com/NanyeonK/macroforecast.git
cd macroforecast
pip install -e ".[dev]"
pip install -e ".[typecheck]"  # optional: local mypy baseline

Quick standalone use

Use individual operations directly as Python callables — no YAML needed:

import macroforecast as mf
import numpy as np

rng = np.random.RandomState(42)
X = rng.randn(100, 5)
y = X @ np.array([1, 2, 3, 4, 5]) + 0.5 * rng.randn(100)

# L4: fit a ridge model
result = mf.functions.ridge_fit(X, y, alpha=1.0)
print(result.summary())
print(result.coef_)

# L5: compute a metric
u1 = mf.functions.theil_u1(y, result.predict(X))
print(f"Theil U1 = {u1:.4f}")

# L7: permutation importance
imp = mf.functions.permutation_importance(result, X, y, n_repeats=10, random_state=42)
print(imp.importances_mean_)

Or use the recipe DSL for full reproducible studies — see docs/index.md and docs/two_entry_points.md for a decision guide.

5-line quickstart

import macroforecast

result = macroforecast.run("recipe.yaml", output_directory="out/")
print(result.cells[0].sink_hashes)            # per-cell sink hashes
replication = macroforecast.replicate("out/manifest.json")
assert replication.sink_hashes_match           # bit-exact replication

Architecture (12 layers)

L0 study setup → L1 data → L2 preprocess → L3 features (DAG, 37 ops)
                ↓                                ↓
                L1.5 / L2.5 / L3.5 (diagnostics, default-off)
                                                 ↓
              L4 model (40+ families) → L4.5 → L5 evaluation → L6 tests
                                                                    ↓
                                                  L7 interpretation → L8 output

Operational coverage

Before relying on advanced families/tests in a paper workflow, check docs/recipe_api/runtime_support.md for the exact current path coverage. Some listed families are wired through legacy/specialized paths or optional extras, not necessarily through the minimal core runtime end-to-end.

• 40+ L4 families — linear (8), tree / boosting (8), SVM (3), kNN, MLP, deep NN (3, opt-in via [deep]), AR_p, factor_augmented_ar, BVAR Minnesota / NIW, FAVAR, MRF GTVP (Coulombe 2024), DFM (Mariano-Murasawa MQ Kalman), quantile_regression_forest, bagging.
• 18 L7 figure types — bar / heatmap / pdp / ALE / SHAP family / attribution / IRF with CI / decomp stacked / state choropleth.
• L6 tests — Diebold-Mariano (with HLN + HAC kernels), Clark-West, Giacomini-Rossi (simulated CVs), MCS / SPA / RC / StepM via stationary bootstrap, Pesaran-Timmermann, residual battery, density tests (PIT-Berkowitz / KS / Kupiec / Christoffersen / Engle-Manganelli DQ), Diebold-Mariano-Pesaran joint multi-horizon.
• L1.G regimes — none / NBER / user-provided / Hamilton MS / Tong SETAR / Bai-Perron breaks.
• 3 sweep kinds — param-level ({sweep: [...]}), recipe-level (external axis), node-level (sweep_groups). Combine via grid (default) or zip.
• Sub-cell parallelism — parallel_unit ∈ {cells, models, oos_dates, horizons, targets}.
• Bit-exact replication — replicate() re-executes and verifies per-cell sink hashes match.

Status levels

Two-value vocabulary (defined in macroforecast.core.status):

• operational — runtime executes the full design-spec procedure.
• future — schema-only; validator hard-rejects, runtime raises NotImplementedError.

The package shipped 19 honesty-pass demotions in v0.1.1; all of them have real implementations in v0.2 / v0.25 / v0.3 (every future flag in the v0.1.1 audit table is now operational).
