Abstract

Using Bayesian Approach in Handling Mortality Ratios Deviations was emerged as this research
idea to meet the need of a scientific model handling the deviations resulting from using
standard mortality tables that are inconsistent with the nature of the Egyptian context,where
Bayesian is a high degree of precision statistical estimation approach depends on mixing
information derived from previous experience with newly collected data, has a high degree of
precision. The fundamental and influential difference between mortality rates derived from the
experience outcomes in the Egyptian market and mortality rates derived from tables used in
pricing of life insurance contracts. The results found the equation of the general trend line for
safety margin rates is a sixth-degreepolynomial equation with a significant level of
99%. Equation used to calculate the value of mortality rates based on tabular values was
estimated.

Key words: Bayesian approach, mortality rates, life insurance contracts.
