brendonmcconnell/Optimal.sample: Optimal Sample Design for Cluster Randomized Trial with Different Costs in Treatment that in Control.

This package provides the optimal sample design (number of treatment and control clusters and number units sampled within treatment and control clusters) for a Cluster Randomized Control Trial to either maximize power subject to a cost constraint or minimize costs subject to a given level of power. The outcome variable is assumed to be continuous, and to be available only at endline (post treatment).
