| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In applications of reliability analyses, a dataset may be collected during a period of time to observe failure events. Left-truncation occurrs for failures occurring before the data collection, and right-censoring arises for failures occurring after the data collection period. The goal of the paper is to review the existing models and methods for dealing with left-truncation and right-censoring for field failure data. Our review includes the existing statistical models, such as the exponential, Weibull, lognormal, gamma, Gompertz, Lomax, and spline models. We comprehensively review the statistical method of maximum likelihood estimation, model selection, residual lifetime prediction, and Bayesian methods. | |
