Wanted to hype up a software package I'm debuting today. If you do computer adaptive testing (CAT) research and are developing your own item selection/parameter update/exposure control algorithms, take a look at meow - a unified framework to make CAT simulation easier! klintkanopka.com/meow/

Apparently some people like listening to me blather on about things! Thanks to @crahal.com for inviting me, this seminar has some amazing speakers lined up and brilliant attendees.

Incredibly proud of the work @ruitings.bsky.social did, and it’s even more impressive that she just finished the first year of her master’s program!

I gave my first conference paper presentation at IMPS 2025 on process data analysis (credits to my amazing advisor @klint.bsky.social for all his support and advice) I also did my first data challenge and got a third prize (credits to my wonderful teammates Jessie and Na) #IMPS2025 #Psychometrics

@ramina-sotoudeh.bsky.social gave an AMAZING talk yesterday as part of the #metrics-and-models seminar series👏. Next (30.07), we have @klint.bsky.social on "Reproducing Expert Judgement with Shortened Surveys using Simulated Annealing"🔥! See website for more; metrics-and-models.github.io!

Thank you @psychonomicsociety.bsky.social for featuring our study! @jyeatman.bsky.social @klint.bsky.social

Shoutouts to @pmetricsoc.bsky.social and University of Minnesota Ed Psych for having the most unhinged (free) conference merch I’ve ever seen

🔥Coming July 2: 'Metrics and Models'!🔥 A new seminar series on advanced modelling w/ impact across health/society. 🌍 Open to *ALL*! 🕑 Weds 2pm UK alternating weeks (online) 🔗 metrics-and-models.github.io 📬 [email protected] Brilliant speakers. *Please share*!

Join us for our last (hybrid) PRIISM seminar of the academic year on 5/7! @austin-van-loon.bsky.social will present an experiment looking at how generative AI in admission essays may reshape the demographics of admitted students and how merit is evaluated. RSVP: steinhardt.nyu.edu/events/compe...

Anyone interested in learning social network analysis in R? I'll be teaching a workshop soon. May 15/16th. umd-cilvr.catalog.instructure.com/courses/intr...

Join us at the intersection of causal inference and psychometrics as we host Josh Gilbert (@jbgilbert.bsky.social) at the PRIISM Seminar. Wednesday @ 10a: Estimating heterogeneous treatment effects with item-level data: Insights from Item Response Theory steinhardt.nyu.edu/events/estim...

Incredibly excited to have this finally come out! Model evaluation should be about comparisons, so we have a metric that puts comparisons in predictive performance on a common scale. I can’t make a thread about this better than @crahal.com, so I’ll let him take it away.

Saw something nice on a walk today

"Cool"

I've said this before, but the single greatest force holding back psychometric research is data availability. Researching innovative assessments requires response data, but those data are owned by those who own the assessments. This gives them carte blanche to gatekeep who can do this work. 1/2

Research with restricted-use data is more precise, powerful, and relevant. Faculty and staff will be working through the weekend to answer important research questions before we no longer can. This is not normal, necessary, or efficient.

The loss of the NAEP restricted-use process data is crushing. It was the most reasonable to acquire dataset that is useful for actual measurement work (as opposed to nonsense mining). The data hoarding practice of private ed and testing companies harms research and students. They must fill the gap.

Can AI-powered textbots improve survey interviews? Join PRIISM and @soubhikbarari.bsky.social to examine how they can enhance response quality and scalability, while considering challenges in bias and respondent experience. If you're in NYC, join us in person! steinhardt.nyu.edu/events/ai-as...

Today I talked about one of my favorite projects I've never published from. I did an internship at a Large Testing Company and before it ended, they sold the test I was working on to another company. No worries, great guy at LTC was helping negotiate data release for me. Then LTC laid that guy off.

Application review for our Clinical (teaching-based) Assistant Professor of Applied Statistics for Social Science Research position begins on Monday. If you're passionate about methods education and want to work with awesome students and colleagues at NYU, we want you! apply.interfolio.com/162021

On Wed 2/12 at 10a ET, the NYU PRIISM Center is hosting Professor Alfonso J Martinez from Fordham University to talk about building adaptive assessments with continuous response formats. The talk is available online and open to the public. More info and RSVP here: steinhardt.nyu.edu/events/build...

Come work with us at an amazing department in an amazing city with amazing colleagues and students. Happy to talk to anyone who is interested! Application review begins Feb 10. apply.interfolio.com/162021

Look at this amazing gift for Onions embroidered by @nonsequiteuse.bsky.social

So proud of the hard work of @anyawma.bsky.social on this paper!

Talking to @kmatheny.bsky.social and realized my true second line of research is "fixing problems people mention in casual conversation with stats and code."

Settling back into the office and writing, but really just thinking about scenic train rides in Jim Thorpe, PA.

Onions 4ever!!

Welcome new followers. You came for Onions, but feel free to stay for psychometrics and computational social science

One of the hardest parts of getting started in psychometric research is data access. The IRW is a place that can really support researchers at all stages of their career!

Two in one day! Out now in @pnas.org: When estimating causal genetic effects, typical sibling studies require genetic information from both siblings. Sam Trejo and I present the Phenotype Differences model, which allows you to do the job with only one genotyped sibling. www.pnas.org/doi/10.1073/...

New paper out in the Journal of Educational and Behavioral Statistics! What happens when probability of correct response depends on item position? Is this a function of items or respondents? We put forward a continuous mixture IRT model to investigate just this! journals.sagepub.com/doi/10.3102/...

I want to talk about how I’m excited to teach parallelization in my Statistical Computing course, but I think most of my followers are here because of Onions. So here he is.

Meet Onions.

Are you looking for a smaller conference focused on the practice and philosophy of measurement? Check out IOMW, happening April 21-22, 2025 in (lovely) Boulder, CO. Featuring a keynote address from the excellent @mijke.bsky.social ! Proposal deadline is 12/16. More information at: www.iomw.net

If you're a Mac user and you find that after updating to 15.1 that you're having trouble with RStudio being unable to connect to R sessions, turn off Apple Intelligence. Apple Intelligence hogs memory, causing rsession-amd64 to lock up

I have to get used to posting over here. If you (or a student) are interested, I'd love to discuss our new PhD program (apps due 12/1). We have a wide range of expertise (psychometrics, ML, causal inference, and more) and are focused on solving applied problems! steinhardt.nyu.edu/degree/phd-s...

Have you ever wondered if the mode of administration matters for depression screeners? Does it matter if it's administered face-to-face or on paper? Check this out: academicminute.org/2024/10/daph...

Next semester I'm teaching an unsupervised learning/measurement course that I've had in my head for a few years now and today I started writing a Quarto Book for it. I'm *irrationally* excited.

My department at NYU is hiring a computational social scientist. Applications come due Monday - happy to chat about the position and department (spoiler: I love it here). apply.interfolio.com/130524

One thing I'm really going to miss about the Bay Area is the MTG community I've found. Anyone play Modern or Legacy (in paper) in/around NYC?

I think I may have just gone grocery shopping for the last time as a Californian.
