On the Nature of the Function Expressive of the Law of Human Mortality

  • David P. Smith
  • Nathan Keyfitz
Part of the Demographic Research Monographs book series (DEMOGRAPHIC)


We omit Gompertz’ method of fitting, which the reader will find in Makeham, below. Also omitted are Gompertz’ mortality tables, and his discussion of life expectancy and annuities under his Law. The hyperbolic logarithms in Art. 5 are the natural logs; we are not able to follow completely his integration, which is by Newton's method of fluxions.
