odr: Optimal Design and Statistical Power of Multilevel Randomized Trials

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. The references for the proposed methods are: (1) Shen, Z. (2019). Optimal sample allocation in multilevel Experiments. (Doctoral dissertation). University of Cincinnati, Cincinnati, OH.
