🤩 Fantastic new network plotting package available in Python by Fabio Zanini. The package supports both networkx and igraph networks, and has a wide variety of styling options. iplotx.readthedocs.io/en/latest/
Gallery of various network visualisations.

Was asked about collinearity again, so here's Vahove's 2019 post on why it isn't a problem that needs a solution. Design the model(s) to answer a formal question and free your mind janhove.github.io/posts/2019-0...

tl;dr

    Collinearity is a form of lack of information that is appropriately reflected in the output of your statistical model.
    When collinearity is associated with interpretational difficulties, these difficulties aren’t caused by the collinearity itself. Rather, they reveal that the model was poorly specified (in that it answers a question different to the one of interest), that the analyst overly focuses on significance rather than estimates and the uncertainty about them or that the analyst took a mental shortcut in interpreting the model that could’ve also led them astray in the absence of collinearity.
    If you do decide to “deal with” collinearity, make sure you can still answer the question of interest.

Plan U, for universal, is the necessary standard. Post everything as a preprint at or before point of submission. Then publish in any journal you want but never pay exorbitant APCs.

Currently attending a conference & our field is quite a bit into fancy modeling, so it’s time to repost this blog post.

Don’t try to squeeze your research question into whatever model is fashionable right now; try to build the right model for your research question.

Is research performance related to academic freedom? A preprint co-authored with @lutzb.bsky.social conducts a large-scale empirical analysis on the national level to this question. osf.io/2mh8f #academicfreedom #AcademicFreedomIndex Short 🧵

“In Finland, the number of homeless people has fallen sharply. Those affected receive a small apartment & counselling with no preconditions. 4 out of 5 people affected make their way back into a stable life. And all this is CHEAPER than accepting homelessness.”

It costs a lot less to house people.
Finland ends homelessness and provides shelter for all in need - scoop.me
In Finland, the number of homeless people has fallen sharply. Why? The country applies the "Housing First" concept agains homelessness.

Remember, if you encounter what seems like an implausible survey finding, ask:
1. Were survey respondents selected randomly or was this an opt-in poll?
2. Could the results, especially for young adults, be driven by bogus respondents?

Keep this post in mind: www.pewresearch.org/short-reads/... 🧪
In an experiment, Pew Research Center demonstrated that opt-in and probability-based surveys produced very different results about young adults' views of the Holocaust and abortion.

Why hasn't Preprint Peer Review caught on more?

I discovered a small, but simple reason - authors are missing out on the JOY of getting feedback because they aren't notified when feedback occurs.

We should switch from paper to screen posters—more eco-friendly and far more engaging. Elisa’s poster already showed us how creative this can be.

eLife (talk by Nicola Adamson) uses a publish-review-curate method and uses common terms to assess manuscripts.

For strength of evidence: exceptional, compelling, convincing, solid, incomplete, & inadequate

For significance of findings: landmark, fundamental, important, valuable, & useful

Elite journals have profound influence in science discourse/careers - a lot of submissions get desk-rejected.

I realize the world is burning, but here is the abstract of a talk I will give multiple times in different formats this month. With the feedback, I hope to write up something substantial on the theme in the remainder of the year.
Statistical algorithms have advanced rapidly in the last
decades, but most researchers are still only taught how to do t-tests
and worry about normality of residuals. At the heart of the
reproducibility crisis lies scientific workflow, the often
unprincipled and undocumented ways that scientific theories are
related to statistical procedures and their results. I want to center
scientific workflow in debates about open science and outline a
research program for taking scientific workflow seriously.
