In esDesign: Adaptive Enrichment Designs with Sample Size Re-Estimation

Description

The sSize.norm() is used to calculate the sample size used in the standard design with continuous endpoint.

Usage

sSize.norm(alpha, beta, theta, side, r, sigma2)

Arguments

alpha	The Type I error rate or the significant level
beta	beta The (1 -Power)
theta	The size of treatment effect
side	One-sided or two-sided Test
r	The ratio of sample size between the experimental and control arms
sigma2	The variance of the treatment effect

Value

A list contains the total sample size, and the sample sizes required for the experimental and control arms.

Examples

alpha <- 0.05
beta <- 0.2
theta <- 0.2
side <- 1
r <- 1
sigma2 <- 0.8
sSize.norm(alpha = alpha, beta = beta, theta = theta,
side = side, r = r, sigma2 = sigma2)
