Score Forecast
Score a forecast dataframe against actuals — horizons, MAPE, WMAPE, and more.
Scores a forecast handed to it against actuals, without owning either.
The general-purpose scorer: ForecastBacktest goes and finds a module's past runs, this one scores whatever is wired into it. Leave actuals unconnected and it resolves them from the twin named in settings instead.

Parameters
digitalTwinId
string · optional · defaults to ""
The twin actuals are resolved from when the actuals port is unconnected.
digitalTwinVersionIds
string[] · optional · defaults to []
Pin the scoring to specific twin versions; empty means the latest.
horizons
number[] · optional
The 1-based lead times to score; omit for defaults derived from the forecast's own horizon.
primaryHorizon
number · optional
The lead time a KPI tile reads; must be in horizons.
metrics
string[] · optional · defaults to ["mape","wmape","mae","mse","rmse","bias","coverage"]
Which accuracy metrics to compute: mape, wmape, mae, mse, rmse, bias, coverage.
primaryMetric
string · optional · defaults to "mape"
The one a KPI tile and the trend read; must be in metrics.
forecastH
number · optional
The forecast horizon, when it cannot be read off the forecast itself.
Inputs
on
event
no
Implicit on every module that does not itself start a flow: wire an event here to make this module the start of what that event runs.
forecast
dataframe
yes
The forecast to score, in the shape ForecastSim emits.
actuals
dataframe
no
What really happened; unconnected, these are read from the twin.
Outputs
comparison
dataframe
dataframe, signal
One row per forecast point beside its actual.
metrics
dataframe
dataframe, signal
Every metric in metrics, for the forecast as a whole.
byHorizon
dataframe
dataframe, signal
The same metrics split by lead time.
summary
dataframe
dataframe, signal
