Kokkuvõte	The Coale-Demeny regional model life tables are a system of standard age patterns of mortality, distilled from hundreds of empirical life tables into four regional families — North, South, East, and West — each indexed by a mortality level. Given only a single summary of mortality, such as life expectancy at birth or a child-survival measure, the system supplies a complete, internally consistent age schedule of death rates. For decades they have been the default tool for inferring full mortality patterns in populations with incomplete or unreliable death data, especially in developing countries and historical demography.	The Brass relational logit model is a two-parameter system for representing and smoothing a life table by relating it to a chosen standard. Introduced by William Brass in 1971, it transforms the survivorship function with a logit and posits that the logits of any two life tables are linearly related, so that an entire age pattern of mortality can be summarized by just two parameters — a level parameter and a parameter governing the balance of childhood versus adult mortality.
