요약	The Coale-McNeil model is a parametric description of how first marriages are distributed by age. Ansley Coale and Donald McNeil showed in 1972 that the age pattern of first marriage in widely different populations has a common shape, captured by a single standard curve that can be shifted and stretched. Three parameters — an origin age at which marriage starts, a scale that controls how spread out the process is, and the ultimate proportion who ever marry — reproduce almost any observed first-marriage schedule, giving demographers a compact and comparable summary of nuptiality.	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.
