In alishinski/CRTpower: Power Analysis for Cluster Randomized trials

Description

MDES for 2-Level Random Effects Blocked Individual Random Assignment

Usage

BIRA2_1r(R2_1, R2_2T, P, g, n, J, rho, omega, alpha = 0.05, power = 0.8,
  tails = 2)

Arguments

R2_1	Proportion of variance in level 1 outcome explained by level 1 covariates
R2_2T	Proportion of between block variance in treatment effect explained by Level 2 covariates
P	Proportion of level 1 units randomized to the treatment
g	Number of level 2 covariates
n	Average Block Size (mean # of level 1 units per level 2 unit)
J	Number of level 2 units
rho	proportion of variance in outcome between clusters
omega	Treatment effect heterogeneity: variability in treatment effects across Level 2 units, standardized by the variability in the Level-2 outcome
alpha	Probability of a type I error
power	Statistical power (1 - probability of type II error)
tails	One or two tailed test

Value

Minimum Detectable Effect Size
