Sample Size or Power Calculation for One-Sample Normal Mean Test
Description
Calculates sample size or power for a two-sample normal mean test.
Usage
one_norm_size(mu, mu0, sd, alpha, beta = NULL, n = NULL)
Arguments
mu |
Numeric. True mean. |
mu0 |
Numeric. Null hypothesis mean. |
sd |
Numeric. Standard deviation. |
alpha |
Numeric. Type I error rate. |
beta |
Numeric (optional). Type II error rate. Required for sample size calculation. |
n |
Integer (optional). Sample size. Required for power calculation. |
Value
Numeric. Returns sample size (if beta
is given), or power (if n
is given).
Note
Only one of beta
(for sample size calculation) or n
(for power calculation) should be specified.
Required arguments:
For sample size:
"mu"
,"mu0"
,"sd"
,"alpha"
,"beta"
For power:
"mu"
,"mu0"
,"sd"
,"alpha"
,"n"
Examples
# Sample size
one_norm_size(mu = 2, mu0 = 1.5, sd = 1,
alpha = 0.05, beta = 0.2)
# Power
one_norm_size(mu = 2, mu0 = 1.5, sd = 1,
alpha = 0.05, n = 32)
