NEW · HUGDRIGO PROJECT 102

From signals to smarter decisions.

One workspace for rolling backtests, model selection, scenario planning and a readable audit trail. Built for clarity, not black-box claims.

Demo environment. All source values are fictional. Backtest accuracy measures this example series and is not a guarantee of future performance.

Operating implications

Trustworthy analysis

What this studio does and does not do

01
Train on earlier observations

Each test point uses only values that existed before it.

02
Show competing models

Compare naive, average, smoothing, trend and seasonal methods.

03
Disclose uncertainty

Bands are heuristic residual-based ranges, not calibrated probability intervals.

Interactive planning

Forecast Lab

Choose a transparent forecasting model, vary future demand and compare possible operating environments.

⌁

Simulation controls

Settings apply to future periods only; historical observations stay unchanged.

Archived observations are preserved. The forecast uses only active months, sorted chronologically. Missing months in the active series are rejected for time-series calculations.

Forecasting methods

Deliberately simple baselines for intelligible comparison

01
Naive

Projects the most recent observation into future months.

02
Moving average

Uses the latest three observations, with recursive updates for future steps.

03
Exponential smoothing

Uses alpha = 0.35; the fitted level carries forward.

04
Linear trend

Ordinary least squares against month index; projected values cannot be negative.

05
Seasonal naive

Repeats the value from 12 months earlier, including recursively after one year.

Portable local workspace

JSON backup

Checks version, length, month format, uniqueness, value bounds and preferences before replacing local data.

Important methodological limits

Responsible interpretation of a toy forecasting system

Fictional observations only. The original series is synthetic and is not a business forecast. This is a transparent educational demonstration, not an AI-trained model, certified planning engine or investment recommendation. Seasonal naive requires 12 historical months. Chronological backtesting uses one-step horizons only. The displayed uncertainty proxy uses a residual quantile scaled by the square root of the forecast horizon; it is not a validated prediction interval.
