title: Computer-assisted predictive formulas expressing survival probability and life expectancy in US adults, men and women, 2001.
abstract: The National Center for Health Statistics (NCHS) reported the United States life tables, 2001 for US total, male and female populations on the basis of 2001 mortality statistics, the 2000 decennial census and the data from the Medicare program [E. Arias, United State life tables, 2001, Natl. Vital Stat. Rep. 52 (2004) 1-40]. The life tables show life expectancy, survival and death rate at each year between birth and 100 years of age. In this study formulas expressing survival probability and life expectancy in US adults, men and women are constructed from the data of the NCHS. A model of the 'probacent'-probability equation previously published by the author is employed in the study. Analysis of the formula-predicted values and the NCHS-reported data indicates that the formulas are accurate and reliable with a close agreement. The formula representing a generalized lognormal distribution might be useful for biomedical investigation, and epidemiological and demographic studies in US adults, men and women.
