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.

I argue that multilevel modeling is a principled way to explore human variation and commonality.

My new book, Multilevel Thinking, is now published in Electronic version by Oxford University Press: academic.oup.com/book/60530. #stata #rstats #julialang

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.
