    This study shows that the Gompertz law of mortality can provide quick, accurate survival predictions. It also offers simple solutions for cause-specific mortality and the impact of removing death causes.

    Area of Science:

    • Actuarial science
    • Demography
    • Biostatistics

    Background:

    • The Gompertz law of mortality is a widely used model in survival analysis.
    • Pollard (1991) previously demonstrated its utility for survival queries.
    • Multiple decrement life tables are essential for analyzing competing risks.

    Purpose of the Study:

    • To extend Pollard's (1991) Gompertz law applications to multiple decrement life tables.
    • To derive simple formulas for cause-specific mortality probabilities.
    • To assess the impact of eliminating specific causes of death.

    Main Methods:

    • Utilizing Pollard's (1991) formulae within the framework of multiple decrement life tables.
    • Developing approximations for cause-specific mortality.

  • Investigating the Gompertz curve as an approximation for grouped causes of death.

    • Main Results:

    • Pollard's (1991) Gompertz-based formulae can be adapted for multiple decrement scenarios.
    • Simple solutions are obtainable for probabilities of death by cause.
    • The effect of eliminating a cause of death can be effectively modeled.

    Conclusions:

    • The Gompertz law offers a valuable approximation for analyzing survival data, even with multiple causes of death.
    • This approach simplifies complex calculations in actuarial and demographic studies.
    • Grouping causes of death can enhance the applicability of the Gompertz model.
