Abstract

apc is a Stata package for estimating age-period-cohort models. apc_cglim estimates generalized linear models in which a single equality constraint on the coefficients is used to solve the age-period-cohort identification problem. apc_ie estimates generalized linear models with age, period and cohort effects using the intrinsic estimator (IE) described by Yang, Fu and Land (Sociological Methodology, 2004). The IE employs a special principal components regression that removes the influence of the null (column) space of the design matrix on the estimator. Both commands are implemented as wrappers for Stata's glm command.
