We develop an R package APCI (and Stata command apci) to implement the age-period-cohort-interaction (APC-I) model for estimating and testing age, period, and cohort patterns in various types of outcomes for pooled cross-sectional data and multi-cohort panel data. Package APC...

the model was better for a full APC model than any combination of age, period, and cohort components (Supplementary Table S1). Analyses were conducted using the Joinpoint Regression Program V.4.7.0.0 (National Cancer Institute, 2019) and Stata V.15.1 (Stata- Corp., College Station, Texas)....
The age–period–cohort model can be expressed as follows: Yj ¼ μ þ α agej þ β periodj þ γ cohortj þ εi where Yj denotes the response variable of the net effect on migraine incidence for group j, α, β, and γ denote the coefficients of age, period, and birth ...
This cohort study examines the association between older age (≥75 years) and the risk of postcolonoscopy complications in a sample of outpatients in
