# Analysis3054 – Advanced Forecasting & Analytics

Analysis3054 is a full‑featured time‑series analytics and forecasting package designed for commodity, energy, and demand‑planning teams. It combines plotting, statistics, machine learning, deep learning (Chronos‑2), physics‑inspired forecasters, and high‑speed data ingestion under a single, unified API.

## Installation
Analysis3054 ships prebuilt wheels for common platforms. A minimal install pulls Chronos‑2, physics forecasters, and AutoGluon backends by default.

```bash
pip install analysis3054
```

Optional extras let you control the footprint per environment:

```bash
pip install "analysis3054[stats]"    # pmdarima + arch
pip install "analysis3054[ml]"       # scikit-learn + boosted trees
pip install "analysis3054[dl]"       # tensorflow
pip install "analysis3054[prophet]"  # prophet + neuralprophet
pip install "analysis3054[tbats]"    # tbats
pip install "analysis3054[all]"      # everything (same as base but explicit)
```

For air‑gapped or offline environments, install from an internal index mirror and export the `ANALYSIS3054_HOME` environment variable to control cache locations for pretrained Chronos‑2 checkpoints.

## What’s new in Chronos‑2
Chronos‑2 now delivers faster inference, richer covariate handling, and clearer diagnostics:

* **Adaptive covariate gating** – detect and down‑weight noisy drivers automatically.
* **Scenario packets** – emit multiple forecast paths per call for stress testing.
* **Quantile fan** – calibrated 5–95% bands optimized for medium‑horizon energy curves.
* **Batch streaming** – stream partial results back to dashboards before the full job completes.

### Chronos‑2 quickstarts
#### Univariate baseline (minimal inputs)
```python
from analysis3054 import chronos2_univariate_forecast

forecast = chronos2_univariate_forecast(
    df,                     # DataFrame with a datetime column and one numeric target
    date_col="date",
    target_col="price",
    prediction_length=14,
    quantiles=[0.05, 0.5, 0.95],
)
print(forecast.forecasts.tail())      # includes scenario packet IDs
print(forecast.diagnostics.summary)   # convergence + latency insights
```

#### Multivariate with automatic covariate gating
```python
from analysis3054 import chronos2_multivariate_forecast

multi = chronos2_multivariate_forecast(
    df,
    date_col="date",
    target_cols=["north", "south", "west"],
    covariate_cols=["temp", "load_forecast"],
    prediction_length=21,
    gate_covariates=True,            # drop unhelpful drivers per series
    scenario_paths=5,                # request multiple stress paths
)
print(multi.forecasts.columns)       # (series, quantile, scenario)
```

#### Covariate‑informed future window
```python
from analysis3054 import chronos2_covariate_forecast

# known drivers during the forecast horizon (weather + planned outages)
future_cov = pd.DataFrame({
    "date": pd.date_range(df["date"].max() + pd.Timedelta(days=1), periods=30, freq="D"),
    "temp": 65,
    "planned_outage": [0, 0, 1, 1, 0] * 6,
})

guided = chronos2_covariate_forecast(
    df,
    date_col="date",
    target_col="price",
    covariate_cols=["temp", "planned_outage"],
    future_cov_df=future_cov,
    prediction_length=30,
    quantiles=[0.1, 0.25, 0.5, 0.75, 0.9],
)
guided.plot_quantile_fan().show()
```

## Physics forecasters
Physics‑inspired models capture conservation relationships and engineered dynamics that traditional ML misses. The helpers accept the same DataFrame shape used across the package, making them drop‑in replacements.

### Mass‑balance forecaster
Ideal for refinery yield or inventory reconciliation problems.

```python
from analysis3054 import mass_balance_forecast

forecast = mass_balance_forecast(
    df,
    date_col="date",
    inflow_cols=["crude_intake"],
    outflow_cols=["products"],
    storage_col="tank_level",
    prediction_length=14,
    enforce_conservation=True,
)
print(forecast.forecasts[["tank_level_mean"]].tail())
```

### Thermal decay forecaster
Captures lagged response between ambient temperature and process temperature.

```python
from analysis3054 import thermal_decay_forecast

thermal = thermal_decay_forecast(
    df,
    date_col="date",
    target_col="process_temp",
    ambient_col="ambient_temp",
    time_constant_hours=6,
    prediction_length=48,
)
thermal.forecasts.plot(title="Thermal response");
```

### Hydro forecast with snowmelt dynamics
```python
from analysis3054 import hydro_snowmelt_forecast

snowmelt = hydro_snowmelt_forecast(
    df,
    date_col="date",
    precip_col="precip_in",
    temp_col="temp_f",
    target_col="river_cfs",
    prediction_length=10,
    melt_threshold=32,
)
print(snowmelt.diagnostics.water_balance)
```

## Lightning‑fast API ingestion
`fetch_apis_to_dataframe` pools HTTP/2 connections, batches retries, and streams partial frames so you can ingest many endpoints into one DataFrame without manual plumbing.

```python
from analysis3054 import fetch_apis_to_dataframe

endpoints = [
    "https://api.example.com/v1/events",                 # simple URL
    {"url": "https://api.example.com/v1/users", "params": {"page": 1}},
    {"url": "https://api.example.com/v1/prices.ndjson", "format": "ndjson"},
]

df = fetch_apis_to_dataframe(
    endpoints,
    max_workers=24,                   # aggressive concurrency
    timeout="5s",                    # per‑request timeout with auto backoff
    sort_by=["timestamp", "region"],
    transform=lambda frame: frame.assign(
        value_pct=frame["value"] / frame["value"].sum()
    ),
    stream_results=True,             # yield partial frames for dashboards
    output_dir="./exports",          # optional CSV persistence
    file_name="daily_snapshot",
)
print(df.head())
```

### Background ingestion for UI threads
```python
future = fetch_apis_to_dataframe(
    endpoints,
    max_workers=12,
    run_in_background=True,          # returns a Future immediately
    throttle_after=0.5,              # adaptive throttle after 429s or timeouts
)

# do other work here ...
df_async = future.result()           # blocks only when results are needed
```

`transform` accepts both regular and async callables. When `stream_results=True`, each partial DataFrame is passed through the transform before being concatenated, ensuring your downstream math stays consistent while the ingestion speeds ahead.

## Quickstart (forecasting)
Create a small demo DataFrame (weekly power prices with a covariate) and run a unified forecast.

```python
import numpy as np
import pandas as pd
from analysis3054 import ForecastEngine

rng = pd.date_range("2020-01-05", periods=120, freq="W")
df = pd.DataFrame({
    "date": rng,
    "price": 50 + np.sin(np.arange(120) / 6) * 5 + np.random.randn(120),
    "temp": 30 + np.random.randn(120),
})

engine = ForecastEngine.default()
forecast = engine.run(
    df=df,
    date_col="date",
    target_cols=["price"],
    horizon=8,
    covariate_cols=["temp"],
)
print(forecast.forecasts.head())
```

## Plotting
### Five‑Year Band Plot
```python
from analysis3054 import five_year_plot

fig = five_year_plot(date="date", df=df, smooth=True)
fig.show()
```

## ML & Robust Forecasters
All ML helpers infer frequency, propagate covariates, apply exponential error correction, and handle missing scikit‑learn gracefully.

```python
from analysis3054 import (
    bayesian_ridge_forecast,
    huber_forecast,
    pls_forecast,
    fourier_ridge_forecast,
    histgb_direct_forecast,
)

ridge = bayesian_ridge_forecast(df, "date", "price", covariate_cols=["temp"], prediction_length=10)
huber = huber_forecast(df, "date", "price", covariate_cols=["temp"], prediction_length=10)
pls = pls_forecast(df, "date", "price", covariate_cols=["temp"], prediction_length=10)
fourier = fourier_ridge_forecast(df, "date", "price", covariate_cols=["temp"], prediction_length=10, seasonal_periods=[52])
histgb = histgb_direct_forecast(df, "date", "price", covariate_cols=["temp"], prediction_length=10, max_depth=4)
```

### Auto ML family (10+ helpers)
```python
from analysis3054 import (
    chronos2_auto_covariate_forecast,
    boosted_tree_forecast,
    random_forest_forecast,
    elastic_net_forecast,
    xgboost_forecast,
    catboost_forecast,
    lightgbm_forecast,
    svr_forecast,
    mlp_forecast,
    harmonic_regression_forecast,
    intraday_sarimax_forecast,
)

auto = chronos2_auto_covariate_forecast(df, "date", "price", covariate_cols=["temp"], prediction_length=6)
boosted = boosted_tree_forecast(df, "date", "price", covariate_cols=["temp"], prediction_length=6)
```

### Leaderboards & Ensembles
```python
from analysis3054 import model_leaderboard, simple_ensemble

leaderboard = model_leaderboard(df, "date", "price", covariate_cols=["temp"], prediction_length=8, models=["chronos2", "sarimax", "harmonic"])
ensemble = simple_ensemble(df, "date", "price", covariate_cols=["temp"], prediction_length=8, models=["chronos2", "harmonic"], weights=[0.7, 0.3])
```
