Finding User Written Stata Command "ddrd"

[Mark Tredwitz]

Hi everyone,

while researching ways to combine difference-in-difference and regression discontinuity designs in Stata, I came ascross this talk from the 2016 Stata conference, mentioning a package called ddrd. However, I was unable to find it using -findit as well as via google. Is there another recommended way to search for packages, or could it be that the program simply is not available anymore?

If anybody knows somethin about it, I'd be very grateful for your help.
Thank you very much in advance.

Best,
Mark

Well -findit- and -search- give no hits for ddrd. I would go to https://www.stata.com/meeting/chicago16/, which is the procedings of the 2016 USA Stata conference (you don't say which user's group it was; if it wasn't the USA, go to the appropriate one) and find the presentation in which it was mentioned. Then contact the author directly.

Alright, thank you very much for your advice.
I just thought there might be another online resource to find those packages, but I'll follow our advice and contact the author directly then.
