sample_size
Description
This function calculates the probability of Type II error for two independent groups when the
when the population standard deviation is assumed known (i.e., using the $z$-distribution)#' in order to achieve a preassigned Type II
error probability (beta) of interest.
Usage
sample_size(mu0, mu1, sigma, alpha, beta)
Arguments
mu0
Mean value 0.
mu1
Mean value 1.
sigma
The standard deviation.
alpha
The Type I error rate.
beta
The desired Type II error rate, used when calculating the
necessary sample size.
Value
Returns the Type II error for a given sample size.
