Time-to-event data, also known as survival data, refers to the time until a specific event occurs, such as death, disease occurrence, or failure of a mechanical system. This type of data is crucial in medical research and reliability engineering because it not only captures the occurrence of the event but also considers the timing of that event. Analyzing this data helps in understanding the efficacy of treatments and interventions over time, as well as comparing the survival experiences of different groups.
