The density function of human lifetime is multimodal and changes rapidly close to zero on its right-hand side. Hence finding good estimators is very difficult. In this paper a kernel estimator of the hazard rate function is proposed. This method was evaluated using computer simulation. Data were generated from a mixture of distributions and from life tables. Using the kernel estimators of density functions, the estimators of lifetime hazard rate functions are given.
