This function estimates power for a continuous variable given the sample size, effect size, significance threshold, and the degrees of freedom.
Usage
eval.power.cont(N, n_coeff, effect, alpha)
Arguments
- N
Sample size
- n_coeff
degrees of freedom for numerator
- effect
effect size
- alpha
significance level (Type 1 error)
Examples
eval.power.cont(N = 1000, n_coeff = 1, effect = 0.0025, alpha = 0.05)
#> N effect alpha power n_coeff
#> [1,] 1000 0.0025 0.05 0.352 1
