What we’re about
Visit our new site at https://nyhackr.org/
Meet with other users of the open-source programming language R. Previously, this meetup focused only on the R language, but is now focused on all open-source data analysis tools; including but not limited to, Python, Julia, C++, Stan, etc.
Learn and share tricks and techniques from and with other users. Beginners to advanced users are all welcome.

- Better Survey Weights Via Regularized RakingNeeds location$7.00
For the last meetup of 2023 we have Andy Timm discussing survey weights.
Thank you to NYU for hosting us.
Everybody attending must RSVP through the registration form at nyhackr.org. There is a charge for in-person and virtual tickets are free. Space is limited and in-person registration closes at 2 PM December 5th.
About the Talk:
Raking is among the most common algorithms for producing survey weights, but it is often opaque what qualities of the resulting weights set are prioritized by the method. This is especially true when practitioners turn to heuristic methods like trimming to improve weights. After reviewing the basic raking algorithm and showing some examples in R, I'll show that survey weighting can also be understood as an optimization problem, one which allows for explicit regularization. In addition to providing a conceptually crisp view of what (vanilla) raking optimizes for, I'll show that this regularized raking (implemented via the rsw python package) can allow for more fine-grained control over weights distributions, and ultimately more accurate weighted estimates. Examples will be drawn from US elections surveys.
Andy is a data scientist who enjoys using modern statistical and machine learning methods to more efficiently solve social science flavored problems (like survey weighting!). Most recently, he was a Data Science Manager at 605, where he worked on problems spanning causal inference, forecasting, and heterogeneous treatment effect modeling. Before 605, Andy worked in politics in a variety of data and field roles. He holds a masters from NYU Gallatin, and a BA from Macalester College.
The venue doors open at 5:30 PM America/New_York where we will continue enjoying pizza together (we encourage the virtual audience to have pizza as well). The talk, and livestream, begins at 6:00 PM America/New_York.
