Animal welfareGlobal health & developmentStatistics
Frontpage

Summary: I'm currently working on a PhD in statistics looking at Bayesian models for data with measurement error, rounded values and missing data. I am interested in finding datasets, either just to use as examples to illustrate my method, or as a more serious project (I would also be open to collaborating with others!), and I think it would be very interesting to work with applications in global health or animal welfare. 

My PhD is very open (scheduled to finish in August 2024), and I'm currently thinking about how I should spend the last 1.3 years of my degree in the best way. I'm also currently struggling a bit creatively with deciding what to do after recently finishing my first paper, which was really the most important part of my PhD, plus it would be very cool if my work could be used for something somewhat useful. I got some advice to ask here, since I'm sure there are a ton of interesting datasets out there that may qualify, and maybe some of you could point me towards them. 

My topic is just Bayesian models for data with measurement error and missing data in the explanatory variables, and so any dataset where we suspect there to be some kind of measurement error and missing data is of interest! I have also been looking a bit into the effects of rounding/data heaping/digit preference and would be super interested in data that suffers from any of these as well (although I don't really know how to "solve" that problem, but that would be something to look into!) If there is already research published using the data, that is just fine (provided I am allowed to use the data), it could be very interesting to see if the conclusions might change if measurement error/rounding/missing data is accounted for, if it was not considered in the original analysis.

So specifically I am interested in the following:

  • Do you know of any datasets with variables that suffer from measurement error, rounded or missing data, that are open to use?
  • Do you have this kind of data and would be open to collaborating with me somehow?
  • More meta: Do you have suggestions for people/organizations to contact or otherwise advice on how to move forward to find these types of data?

If anyone is interested, my paper is available as a preprint on arXiv: https://arxiv.org/abs/2303.15240

I've reached out to some people doing impactful data-driven work in global development, who may be interested in collaborating. 

It's great that you are looking for impactful applications in your PhD, and I wish you the best of luck! I also really appreciate the amount of details and openness in this post :)

Thank you! If you don't mind me asking, how do you tend to go about asking for collaborations with people, if you don't know them from before? I tend to find this "social" part of research very difficult, because I feel like I'm intruding too much or asking too much of people.

The JPAL and IPA Dataverses have data from 200+ RCTs from development economics and the 3ie portal has 500+ studies with datasets available (and you can further filter by study type if you want to limit to RCTs). I can't point you to particular studies that having missing or mismeasured covariates, but from personal experience, a lot of them have lots of missing data.

In recent months, the CEOs of leading AI companies have grown increasingly confident about rapid progress: * OpenAI's Sam Altman: Shifted from saying in November "the rate of progress continues" to declaring in January "we are now confident we know how to build AGI" * Anthropic's Dario Amodei: Stated in January "I'm more confident than I've ever been that we're close to powerful capabilities... in the next 2-3 years" * Google DeepMind's Demis Hassabis: Changed from "as soon as 10 years" in autumn to "probably three to five years away" by January. What explains the shift? Is it just hype? Or could we really have Artificial General Intelligence (AGI)[1] by 2028? In this article, I look at what's driven recent progress, estimate how far those drivers can continue, and explain why they're likely to continue for at least four more years. In particular, while in 2024 progress in LLM chatbots seemed to slow, a new approach started to work: teaching the models to reason using reinforcement learning. In just a year, this let them surpass human PhDs at answering difficult scientific reasoning questions, and achieve expert-level performance on one-hour coding tasks. We don't know how capable AGI will become, but extrapolating the recent rate of progress suggests that, by 2028, we could reach AI models with beyond-human reasoning abilities, expert-level knowledge in every domain, and that can autonomously complete multi-week projects, and progress would likely continue from there.  On this set of software engineering & computer use tasks, in 2020 AI was only able to do tasks that would typically take a human expert a couple of seconds. By 2024, that had risen to almost an hour. If the trend continues, by 2028 it'll reach several weeks.  No longer mere chatbots, these 'agent' models might soon satisfy many people's definitions of AGI — roughly, AI systems that match human performance at most knowledge work (see definition in footnote). This means that, while the compa

SUMMARY:  ALLFED is launching an emergency appeal on the EA Forum due to a serious funding shortfall. Without new support, ALLFED will be forced to cut half our budget in the coming months, drastically reducing our capacity to help build global food system resilience for catastrophic scenarios like nuclear winter, a severe pandemic, or infrastructure breakdown. ALLFED is seeking $800,000 over the course of 2025 to sustain its team, continue policy-relevant research, and move forward with pilot projects that could save lives in a catastrophe. As funding priorities shift toward AI safety, we believe resilient food solutions remain a highly cost-effective way to protect the future. If you’re able to support or share this appeal, please visit allfed.info/donate. Donate to ALLFED FULL ARTICLE: I (David Denkenberger) am writing alongside two of my team-mates, as ALLFED’s co-founder, to ask for your support. This is the first time in Alliance to Feed the Earth in Disaster’s (ALLFED’s) 8 year existence that we have reached out on the EA Forum with a direct funding appeal outside of Marginal Funding Week/our annual updates. I am doing so because ALLFED’s funding situation is serious, and because so much of ALLFED’s progress to date has been made possible through the support, feedback, and collaboration of the EA community.  Read our funding appeal At ALLFED, we are deeply grateful to all our supporters, including the Survival and Flourishing Fund, which has provided the majority of our funding for years. At the end of 2024, we learned we would be receiving far less support than expected due to a shift in SFF’s strategic priorities toward AI safety. Without additional funding, ALLFED will need to shrink. I believe the marginal cost effectiveness for improving the future and saving lives of resilience is competitive with AI Safety, even if timelines are short, because of potential AI-induced catastrophes. That is why we are asking people to donate to this emergency appeal

We’ve written a new report on the threat of AI-enabled coups.  I think this is a very serious risk – comparable in importance to AI takeover but much more neglected.  In fact, AI-enabled coups and AI takeover have pretty similar threat models. To see this, here’s a very basic threat model for AI takeover: 1. Humanity develops superhuman AI 2. Superhuman AI is misaligned and power-seeking 3. Superhuman AI seizes power for itself And now here’s a closely analogous threat model for AI-enabled coups: 1. Humanity develops superhuman AI 2. Superhuman AI is controlled by a small group 3. Superhuman AI seizes power for the small group While the report focuses on the risk that someone seizes power over a country, I think that similar dynamics could allow someone to take over the world. In fact, if someone wanted to take over the world, their best strategy might well be to first stage an AI-enabled coup in the United States (or whichever country leads on superhuman AI), and then go from there to world domination. A single person taking over the world would be really bad. I’ve previously argued that it might even be worse than AI takeover. [1] The concrete threat models for AI-enabled coups that we discuss largely translate like-for-like over to the risk of AI takeover.[2] Similarly, there’s a lot of overlap in the mitigations that help with AI-enabled coups and AI takeover risk — e.g. alignment audits to ensure no human has made AI secretly loyal to them, transparency about AI capabilities, monitoring AI activities for suspicious behaviour, and infosecurity to prevent insiders from tampering with training.  If the world won't slow down AI development based on AI takeover risk (e.g. because there’s isn’t strong evidence for misalignment), then advocating for a slow down based on the risk of AI-enabled coups might be more convincing and achieve many of the same goals.  I really want to encourage readers — especially those at labs or governments — to do something
