SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Visualize and validate forecast backtests by comparing weekly actual outcomes to Monte Carlo cone predictions.

Core Features & Use Cases

  • Supports three views: Forecast Cone, Actual-vs-P50 Gap, Rolling Accuracy, plus a detailed checkpoint table.
  • Integrates with mcs-charts-base to reuse styling, layout, and interaction patterns for consistency.
  • Useful for Walk-Forward Analysis to assess calibration, detect drift, and gauge forecast reliability over time.

Quick Start

Provide forecast_backtest data to render the three-chart visualization and the checkpoint table.

FAQPage Schema
How do I visualize forecast backtest calibration against actual outcomes?

To visualize forecast backtest calibration, compare weekly actual outcomes against Monte Carlo cone predictions. This approach uses three dedicated views to reveal calibration drift and gauge forecast reliability over time.

What is the best way to detect forecast calibration drift during walk-forward analysis?

The best way to detect forecast calibration drift during walk-forward analysis is by visualizing the Actual-vs-P50 Gap view. This chart highlights the variance between actual outcomes and the P50 prediction cone to expose reliability issues.

Can I render a Monte Carlo cone prediction chart for walk-forward analysis data?

Yes, you can render a Monte Carlo cone prediction chart for walk-forward analysis data. By processing forecast_backtest data, the visualization pipeline generates cones alongside a detailed checkpoint table to handle anomalous data points.

Does the backtest visualization support integration with mcs-charts-base styling?

Yes, the backtest visualization supports integration with mcs-charts-base. It reuses styling, layout, and interaction patterns from the base framework to ensure consistent rendering across the forecast cone and rolling accuracy charts.

How do I handle anomalous checkpoints in forecast backtest visualization?

To handle anomalous checkpoints in forecast backtest visualization, the rendering pipeline applies specific data nuance handling. This ensures anomalous data points do not disrupt the cohesive visualization of the forecast cone and rolling accuracy views.
