Bound Constrained Optimal Sample Size Allocation

CRAN Package

Implements bound constrained optimal sample size allocation (BCOSSA) framework described in Bulus & Dong (2021) doi:10.1080/00220973.2019.1636197 for power analysis of multilevel regression discontinuity designs (MRDDs) and multilevel randomized trials (MRTs) with continuous outcomes. Minimum detectable effect size (MDES) and power computations for MRDDs allow polynomial functional form specification for the score variable (with or without interaction with the treatment indicator). See Bulus (2021) doi:10.1080/19345747.2021.1947425.
