Calculates the power for a one-sample t-test given the effect size (d),
total sample size (n), and significance level (alpha).
Usage
power_t_one_sample(d, n, alpha = 0.05, tails = "two")
Arguments
- d
Numeric. The effect size (difference from the constant divided by sigma).
- n
Integer. Total sample size.
- alpha
Numeric. The significance level (default is 0.05).
- tails
Character. "two" for a two-tailed test or "one" for a one-tailed test.
Value
Numeric. The computed power (1 - beta).
Examples
# Calculate power for an effect size of 0.5 with n = 40 subjects
power_t_one_sample(d = 0.5, n = 40, alpha = 0.05)
