Does it provide model evaluation metrics?

Yes, it generates comprehensive reports including MAPE, RMSE, MASE, and directional accuracy to evaluate how well the model performs on unseen data.

What forecasting methods are supported?

The skill supports statistical baselines (ARIMA), business-focused models (Facebook Prophet), deep learning (LSTM/GRU), and multivariate models (VAR).

How do I integrate forecasts into my existing workflow?

The skill uses the SpecWeave increment system to store models, forecasts, and analysis reports in a structured directory, making it easy to sync with your documentation and version control.

How does it handle data leakage in time-series?

Unlike standard ML, this skill enforces temporal order by using chronological train/test splits and expanding window cross-validation to ensure models never 'see' the future during training.

Can I include external factors like holidays or marketing spend?

Yes, the Prophet and Multivariate forecasters allow you to add custom regressors and built-in holiday effects to improve prediction accuracy.
