Data & Statistics
Time Series & Forecasting
ARIMA, SARIMA, exponential smoothing, VAR and Prophet models, validated on held-out data.
A forecast is only worth something if it has been tested against data the model never saw. In-sample fit tells you almost nothing about forecast accuracy.
We test stationarity, difference where required, identify and fit the model, then validate on a hold-out period with reported error metrics and prediction intervals.
What you receive
- Stationarity testing and transformation decisions
- Model identification with ACF/PACF diagnostics
- Out-of-sample validation with MAE, RMSE and MAPE
- Forecasts with prediction intervals
- Reproducible script
