Dear Statlisters,
I'm pleased to announce the new package attcic. This command implements the attrition corrections we propose with Dalia Ghanem, Sarojini Hirshleifer, and Désiré Kédagni in the paper "Correcting Attrition Bias using Changes-in-Changes (J of Econometrics, 2024)." These corrections exploit baseline outcome data to recover the ATT-R, ATE-R, and ATE, and can be applied to randomized experiments as well as quasi-experimental difference-in-difference designs. In addition to these corrections, attcic also reports the results of comparator approaches such as the IPW corrections, Manski bounds, and Lee bounds. For more details, see the paper here.
The program can be installed from SSC by typing the following in the Stata command window:
Once installed, you can read the help file with:
The help file provides several examples of how to use the command and the output table it generates. The earliest version of Stata required to run this routine is Stata 14, and you should have the commands esttab and leebounds installed.
We hope you give it a try!
