Citing a specific calculator

If your study relied on one particular app, name it and its address alongside the reference above, for example the Abnormal Return Calculator (ARC), the Abnormal Volume Calculator (AVC), news analytics (CATA), or the Event Date Identifier (EDI). Reporting the app, the expected-return model, and the estimation and event windows you used makes your results reproducible.

Why citing matters

EventStudyTools has been free for academic use since 2014, funded by goodwill alone. Citations are how we track the tools' scholarly impact and justify continued development, so citing the apps you used directly supports them.
