odr: Optimal Design and Statistical Power of Multilevel Randomized
Trials
Calculate the optimal sample allocation that produces the highest statistical power
for experimental studies under a budget constraint,
perform power analyses with and without accommodating cost structures of sampling, and calculate
the relative efficiency between two sample allocations.
The references
