Pleased to see this out in print - detailing MAIHDA's desirable statistical properties. "MAIHDA is especially valuable when inequalities are subtle or data for marginalised intersections are sparse - conditions common in practice" journals.sagepub.com/doi/10.1177/... @clarerevans.bsky.social

Want to know how to use MAIHDA to examine heterogeniety in policy outcomes? Here's a nice worked-through example! How does intersectional identity impact preference for in-person vs online GP appoinments? Has been great working with @healthfoundation.bsky.social colleagues on this :)

Charles Tallack@charlestallack.bsky.social · 10mo ago

Intersectionality describes how demographic disadvantages can interact to amplify inequalities. But how to model this? New from colleagues in our analysis team: a case study of GP appmts & patient experience, illustrating the MAIDHA intersectional modelling approach. medium.com/healthfdn-da...

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

Julia M. Rohrer@dingdingpeng.the100.ci · last yr.

Does anybody have a good visualization to explain how interactions can be confounded, and why interactions require interaction controls? @urisohn.bsky.social maybe? (Asking because I have an idea, but want to check out what exists already before investing the effort)

Our research on the effects that PIP changes could have on local economies, written by authors @nataliecbennett.bsky.social @profbambra.bsky.social & @lukemunford.bsky.social, was featured on the @itvpeston.bsky.social programme last night - you can watch the episode on catch up

Another q for the stats people! People worry about collinearity (cf blog post below). Consider a scenario in which the collinear predictors are just controls to account for confounding. Including both of them doesn't impair the precision with which the effect of interest is estimated, does it?

It’s my first project too! In fact, it’s also my first in epidemiology since I come from philosophy. :) I find stratified graphs based on social categories (like Hernández-Yumar, 2018) really interesting.

A little story about this article & how teachers make a difference: In 2013, I was a student in a social epidemiology class taught by the esteemed David Williams. He observed, with some frustration while we looked at a series of graphs, that we often lump people into the “Hispanic” category — 1/

New preprint! osf.io/preprints/ps... The age-period-cohort problem is something that many researchers are vaguely aware of. There have been very cool advances in how to reason about it which don't seem to be well-known in psych. So, I've written a primer!

Rereading @andrewjdbell.bsky.social's 2020 paper on APC analysis & this is such a great example of how plots imply certain interpretations of the data. Same underlying data but depending on how you connect the lines, the implied age effect looks completely different.
