Survival Analysis: A Training Decision Application

Abstract

The life of a task in an airman's inventory of tasks performed has not been investigated. How long a task remains (survives) in an individual's task inventory is of interest for training purposes. Survival analysis can possibly be used to measure task survivability. However, survival analysis uses longitudinal data whereas the USAF Occupational Survey Program captures vertical data (i.e., a snapshot is taken of the work force at one moment in time). Nonetheless, because survival analysis can incorporate both time and censored data, it could provide useful information about task survivability. In this effort, a task survival data base was modeled by combining both occupational survey data and known attribution data. Survival analysis functions were then generated. Results show both that survival analysis can be used to study task survivability and that this approach produces accurate estimates of task life.
