odr: Optimal Design and Statistical Power for Experimental Studies
Investigating Main, Mediation, and Moderation Effects
Calculate the optimal sample size allocation that
produces the highest statistical power for experimental
studies under a budget constraint, and
perform power analyses with and without accommodating
cost structures of sampling. The designs cover single-level
and multilevel experiments detecting main, mediation,
and moderation effects (and some combinations).
