title: [Hazard function and life table: an introduction to the failure time analysis].
abstract: Failure time analysis has become popular in demographic studies.  It can be viewed as a part of regression analysis with limited dependent variables as well as a special case of event history analysis and multistate demography.  The idea of hazard function and failure time analysis, however, has not been properly introduced to nor commonly discussed by demographers in Japan.  The concept of hazard function in comparison with life tables is briefly described, where the force of mortality is interchangeable with the hazard rate.  The basic idea of failure time analysis is summarized for the cases of exponential distribution, normal distribution, and proportional hazard models.  The multiple decrement life table is also introduced as an example of lifetime data analysis with cause-specific hazard rates.
