Samenvatting	Static-99, and its age-revised form Static-99R, is the most widely used actuarial instrument for estimating sexual and violent recidivism risk among adult male sexual offenders. It scores ten unchanging, historical risk factors into a total that maps onto a risk category and, via published norm tables, an estimated probability of reoffending — providing a standardized, evidence-based anchor for forensic risk decisions.	Recidivism survival analysis models the time from a release or index event until an individual reoffends, treating reoffending as a time-to-event ('failure') outcome with censoring for those not observed to fail. It applies survival methods — Kaplan-Meier curves, Cox proportional-hazards regression, and split-population models — to answer not just whether someone recidivates but how quickly and what raises or lowers that risk over time.
