Mathematically\, the question amounts to determining whether the endpoint of the underlying lifetime distribution i s finite. Recent analyses of data on the oldest human lifetimes have led t o competing claims about survival and to some controversy\, due in part to incorrect statistical analysis. We provide a critical assessment of some earlier work and illustrate the ideas through reanalysis of semi-supercent enarian lifetime data\, focusing on data quality and sampling schemes\, ch oice of suitable statistical models and adequate extrapolation schemes. Us ing a blend of survival analysis and extreme value theory\, we highlight s ome of the conclusions that can be reasonably reached based on the limited records: although the rate of mortality stabilize around 109 years or so\ , the hazard is very high with a nearly 50% probability of dying in any gi ven year. Our analysis suggests that a limit to human lifespan would be mu ch beyond the range of the records and there is reasonable power to detect a limit below 130 years.\n \n https://lbelzile.bitbucket.io/\n\nWeb site :聽 /epi-biostat-occh/seminars-events/seminars/biostatist ics\n DTSTART:20230215T203000Z DTEND:20230215T213000Z LOCATION:Room 1203\, 9I制作厂免费 College 2001\, CA\, QC\, Montreal\, H3A 1G1\, 2 001\, avenue 9I制作厂免费 College SUMMARY:L茅o Belzile\, HEC Montr茅al URL:/mathstat/channels/event/leo-belzile-hec-montreal- 345752 END:VEVENT END:VCALENDAR
