Waiting-time assumption record StatMedAnalysis | 11 November 2026 Record the time origin and justification for a constant event rate. Define the risk process and document rate stability before using a waiting-time model. Add a hypothetical input and independently compute survival at one planned time. Use synthetic or aggregate values only. Duplicate the blank row for additional records.
