Power Analysis Tools for Individual/Cluster Randomized Trials
Metin Bulus [aut,cre]
Nianbo Dong [aut,cre]
Statistical power analysis tools for designing individual or cluster randomized trials.
Includes functions to calculate statistical power (1 - type II error), minimum detectable effect size (MDES),
minimum required sample size (MRSS), functions to solve constrained optimal sample allocation (COSA) problems,
and to visualize duo or trio relationships between statistical power, MDES, MRSS, and COSA.

Power Analysis Tools for Multilevel Randomized Experiments
Statistical power analysis tools for designing multilevel randomized experiments.
Includes functions to calculate statistical power (1 - type II error), minimum detectable effect size (MDES),
minimum required sample size (MRSS), functions to solve constrained optimal sample allocation (COSA) problems,
and to visualize duo or trio relationships between statistical power, MDES, MRSS, and a component of COSA.

Includes tools to calculate statistical power, minimum detectable effect size, and minimum required sample size for various multilevel randomized experiments with continuous outcomes. Some of the functions can assist with planning two- and three-level cluster-randomized trials (CRTs) sensitive to moderation effects, and with planning two-level CRTs sensitive to 2-2-1 and 2-1-1 mediation effects.
