Description: Calculate the optimal sample allocation that produces smallest variance of a
treatment effect or 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.
