power1L: power1L

In bangtle/PowerRTCRT: Calculates the power for Randomized Trials (RT) and Cluster Randomized Trials (CRT) models.

Description

This function returns the power for single-level randomized trials designs. It addresses the following models:

• Main treatment effects, with no additional covariates.

• Main treatment effects, with covariate(s) at level 1.

Usage

power1L(n, delta, numcovL1 = 0, R2L1 = 0, alpha = 0.05)

Arguments

n	Number of subjects in level 1 (individual level).
delta	Standardized effect size.
numcovL1	Number of covariate(s) at level 1. Default value is 0.
R2L1	R-squared at level 1. Default value is 0.
alpha	Probability of type I error. Default value is 0.05.
