Mathematical modeling of the dependence of the probability density of the age of death of a person on time

Abstract

Dependence of the life expectancy of a person, more accurately the dependence of the probability density of human death on time, is determined by the known regularities of processes that determine mortality. Most often, the process of damage to certain physiological systems that determine the viability of the organism occurs by accumulating small, non-simultaneous damages of such systems. Therefore, there is an analogy between the processes that lead to the death of people by the mechanism that is being discussed, and the mechanism of oncological diseases. This, in turn, means the possibility of describing the processes of people dying with the help of functional dependencies describing the mechanism of carcinogenesis.
