I'll be offering an introduction to #simulation methods to determine #SampleSize-s for clustered / nested studies.

Apparently another popular session at #RMeF23 🙇

One of the classics that got me into this area is Ukoumunne's

I was always interested in how to straddle the overlap between observational #TherapistEffect studies* and #RCTs in this area.

Thrilled that my interview with Kathleen Slaney is billed as one of the "highly attended" sessions of #RMeF23! (N=125)

I am only the interviewer, so please check out her work here:

Read her fantastic book!

Or one of her many interesting publications!
I am currently working my way through "Scientific generalization in psychological inquiry: A concept in need of clarification"
