title: Postnatal mortality from pneumonia.
abstract: Research has been conducted on the relationship between postnatal mortality from pneumonia and age, using data from the USA, Japan, former Czechoslovakia, Italy, Portugal and the UK during the period of 1979-1993. The logarithm of mortality caused by pneumonia fell linearly with the logarithm of age, during the interval of 1-10 years. This linear log-log dependence corresponds to the two-parametrical Weibull distribution, if the slope is greater than -1. However, the logarithm of mortality from pneumonia declined with the slope equal to -1. The mortality from pneumonia is inversely proportional to the age. The risk of death at age of 2 is one half of the risk at the age of 1, at the age of 3 it is one third of the risk of death at the age of 1ellipsis, etc. up to the age of 10. We assumed that no subpopulation susceptible to pneumonia exists and the risk of death from pneumonia applies in whole population. Consequently, there was applied another distribution function described at this paper.
