Quadratic fractional age assumption revisited

Lifetime Data Analysis Aims and scope Submit manuscript

Abstract

This paper introduces a quadratic fractional age assumption which makes the force of mortality and survival function continuous at all ages. The necessary and sufficient condition for the assumption to be valid is derived. Important life table parameters are estimated and applications are shown using several life table data.
