Multiverse simulation to explore the impact of analytical choices on type I and type II errors in a reaction time study - Behavior Research Methods Researcher degrees of freedom in data analysis present significant challenges in social sciences, where different analytical decisions can lead to varying conclusions. In this work, we propose an exam...

I am happy to announce the publication of our new work on the impact of arbitrary analytical choices on type I and type II error rates. We simulated reaction time data in a conflict task and analyzed the notable CSE effect in a multiverse manner. Worrying results:

Possibly, yes, if the data is such that geolocation data would matter. Friesland is a province within the Netherlands with, for instance, their own dialect, so in a study on say language acquisition it might well matter!

You can sign up until April 22 for the next Causal Inference and Variable Control workshop on May 9 by Peder Isager for the Paul Meehl Graduate School. Workshops are free, and fun, so sign up if interested!

Bayes factors for two-group comparisons in Cox regression with an application for reverse-engineering raw data from summary statistics The use of Cox proportional hazards regression to analyze time-to-event data is ubiquitous in biomedical research. Typically, the frequentist framework is used to draw conclusions about whether haz...

Former PhD student Max Linde wrote a paper showcasing a new Bayesian implementation of Cox proportional hazards regression. Out now in Journal of Applied Statistics! doi.org/10.1080/0266...

To interact or not to interact: The pros and cons of including interactions in linear regression models - Behavior Research Methods Interaction effects are very common in the psychological literature. However, interaction effects are typically very small and often fail to replicate. In this study, we conducted a simulation compari...

Excited to share that my first PhD paper got published! We explored the effects of correctly vs. failing to model true interactions in data. Can model misspecification lead to reversed conclusions? Which model generalizes better to a larger sample?

General Triage, Geolocation Data, and Registered Revisions: A Peek Under the Hood of Collabra: Psychology This editorial comes one year after I took the reins of Collabra: Psychology from Simine Vazire. Simine led the journal from 2020 to 2023, and I have had the privilege of working with her during that ...

After my first year as EiC of Collabra: Psychology, I wrote an editorial with my reflections so far. Featured are some observations about submission triage, author geolocation data, and a registered revisions experiment. @collabrapsychology.bsky.social
