Thank you!

Professor at the University of Michigan. I study parenting and child development, most recently using international data, and often using multilevel models. I work in both Stata and R, and am trying to get better at Julia.
Thank you!

New paper on empathy and mental health outcomes. Empathy appears to be a "risky strength". Too much or too little empathy appear to be risk factors, while a moderate amount of empathy appears protective.

A tutorial on reasons for using quantitative methods. Iβve made some updates: minor updates to the diagrams; and notes clarifying the relationship of ideas in the tutorial to ideas about RCTβs, mediation, confounders, and statistical colliders.

Why care about these technicalities?
Interactions are one of our major statistical tools for examining similarity or difference in statistical relationships across groups, identities, or contexts.
Interactions in logistic regression can be particularly challenging to work with: agrogan1.github.io/newstuff/cat...
Both main effects and interactions need to be interpreted together:
agrogan1.github.io/posts/intera...
agrogan1.github.io/posts/intera...
Interactions are often thought of as encompassing a main effect (x), and a moderator (m), but because of the commutative property of multiplication, interactions are essentially symmetric: agrogan1.github.io/posts/intera...
For many models, adding a main effect and interaction for group can be seen as giving each group its own regression line with its own intercept and its own slope:

I argue that multilevel modeling is a principled way to explore human variation and commonality.
I try to provide a tutorial for applied researchers, and to bring "down to earth" some of the more advanced ideas about multilevel modeling that I see in the methodological literature, but rarely see in applied work.

Just similarity and difference across groups or countries, which I think, multilevel models let us start to see. Simply the size of the random slopes. Now that Iβve written the book, I need to figure out even better ways to quantify this.
Iβd like to share that my book, Multilevel Thinking: Discovering Variation, Universals, and Particulars in Cross-Cultural Research is available for pre-order at Oxford University Press: global.oup.com/academic/pro...

We've published a new paper: Spillover of Macro-Level Violence to Parental Physical Abuse of Children in Low- and Middle-Income Countries. The paper should be online shortly, but in the meantime, we've prepared a scrollable summary here: globalfamilies.quarto.pub/spillover-of...
Thank you for the kind words!
