In the classic age–period–cohort (APC) approach a single constraint is used to eliminate the linear dependency and identify the model. Among the infinite number of possible choices for a constraint, a particular constraint has been discovered and rediscovered in multiple guises. This constraint ...
The Age-Period-Cohort model describes the (log-)rates as a sum of (non-linear) age- period- and cohort-effects. The three variables age (at follow-up), a, period (i.e. date of follow-up), p, and cohort (date of birth), c, are related by a = p − c ; any one person'...
Carstensen ∗, †Steno Diabetes Center, Niels Steensens Vej 2, DK 2820 Gentofte, DenmarkSUMMARYAnalysis of rates from disease registers are often reported inadequately because of too coarse tabulationof data and because of confusion about the mechanics of the age–period–cohort model used for ...
Age period cohort model is widely used by epidemiologists to analyse trends of chronic diseases.The statistical model provides a useful modification for traditional descriptive epidemiology.But parameters of age,period and cohort are not uniquely estimable because of the exact linear dependency among the...
n this article, I describe and illustrate Stata programs that facilitate i) the fitting of smooth age–period–cohort models to event data and ii) the plotting of observed and fitted rates. The programs include postestimation functional- ity and flexibility to fit models not possible using Stata...

Since mortality rates reflect the accumulation of health risks15, we further investigated the independent impacts of age, period, and cohort on the long-term trends via an age-period-cohort model (APC) of estimable functions using the same data. Methods Global burden of disease study 2017 The ...
