apc is a Stata package for estimating age-period-cohort models. It 
contains two ado files and an example program.

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 
(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.
