Great work led by Andrew Castillo extending sample size stability analyses to interactions! We've also added a function implementing these analyses to the InteractionPoweR R package: dbaranger.github.io/InteractionP... #rstats

Reliability and sample size have a non-linear relationship. Linear increases in reliability yield diminishing reductions in the required sample size.

If you are ever working on a project and see r=0.98 between variables that are supposedly different, your first thought should be "oh $&*! what went wrong?", NOT "I wonder what mediates this???"
