backtest

backtest

Minimal hit-count backtest for lambda rules.

The first-slice MVP supports "run rule, count hits" only — no label-matching, no precision/recall. The returned :class:BacktestResult still carries the full :class:EventLog so the caller can inspect any individual hit and run their own downstream analysis (e.g. to_event_log_xes for pm4py, filter_by_pack for domain-specific drill-down).

run_backtest

run_backtest(
    detector: LambdaDetector,
    dataframe: DataFrame,
    *,
    objects: Mapping[str, object] | None = None,
    qualifiers: Mapping[str, str] | None = None
) -> BacktestResult

Run detector over dataframe and summarize hit counts.

Parameters:

Name	Type	Description	Default
detector	LambdaDetector	The registered lambda rule.	required
dataframe	DataFrame	Input frame the rule is evaluated on.	required
objects	Mapping[str, object] | None	Object bindings passed to the event-log adapter.	None
qualifiers	Mapping[str, str] | None	Relation qualifier per object type.	None

Returns:

Name	Type	Description
A	BacktestResult	class:BacktestResult with the hit count, hits per severity and
	BacktestResult	per asset, and the full event log.
