| 概要≠ | Bayesian reliability analysis estimates how long components or systems survive — their reliability, failure rate, and lifetime distribution — by combining observed (often censored) failure data with prior knowledge through Bayes' rule. As developed in Hamada, Wilson, Reese, and Martz's Bayesian Reliability (2008), it is especially valuable when failures are rare, tests are expensive, and engineering or historical information must be brought to bear. | The Kaplan-Meier estimator, introduced by Kaplan and Meier in 1958, is a non-parametric method that estimates the survival curve — the probability of remaining event-free over time — from right-censored time-to-event data. The log-rank test is the companion procedure used to compare survival curves between groups. |
