While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

Quite a great tool
Quite a great tool. Very well documented and convinces with several offers for implementation. The only drawback: The upload files can only be 5 MB in size. Unfortunately, this leads to problems with larger even studies.

Thank you for your feedback! We're glad you enjoyed our tool, and your support means a lot to us. Here is how to get each input file up to approx. 15 MB of data: Save your data in CSV format (not XLS), zip each file, and upload the ZIP files. Happy research, your EST team!
The tool itself is very helpful …
The tool itself is very helpful and after a short familiarization easy to understand and use. The page itself could be a bit easier to navigate and additional guidance in the interpretation of the results would be desirable. The ability to view the results in tabular form and possibly graphically would also be very helpful. All in all, however, I am very satisfied with the tool!

Great help for my master's thesis
EST-ARC performed very well on my event study with about 400 events across companies and different indices... It gave me all the returns and test statistics needed for my thesis.
