# Function emptyLifecycleStatisticsModel

- emptyLifecycleStatisticsModel(): LifecycleStatisticsModel

  An empty lifecycle model that callers can use as a fast fallback when the corpus rebuild fails or exceeds its time budget. With this model every lookup returns `undefined` so forecasts gracefully degrade to the `INSUFFICIENT_DATA` heuristic basis without aborting the request.

  #### Returns LifecycleStatisticsModel
