A simulated sample panel data with heterogeneous treatment effects across
cohorts and groups.

datasets

Extends the Changes-in-Changes model a la Athey and Imbens
(2006) <doi:10.1111/j.1468-0262.2006.00668.x> to multiple cohorts and
time periods, which generalizes difference-in-differences estimation
techniques to the entire distribution. Computes quantile treatment
effects for every possible two-by-two combination in ecic(). Then,
aggregating all bootstrap runs adds the standard errors in
summary_ecic(). Results can be plotted with plot_ecic() aggregated
over all cohort-group combinations or in an event-study style for
either individual periods or individual quantiles.
