ssp_power_traditional.Rd
This method is used to estimate the minimum sample size that a design needs to reach a statistical power, given a desired significance level and expected effect size.
ssp_power_traditional(tpr, delta, max_n, alpha = 0.05)
tpr | Numeric. The desired long-run probability of obtaining a significant result with a one-sided t-test, given Delta. |
---|---|
delta | Numeric. The expected population effect size. |
max_n | Integer. The maximum number of participants per group (both groups are assumed to have equal sample size). |
alpha | Numeric. The level of significance. |
The function returns a list of one named numeric vector. The vector called `n1` contains the determined sample size per group for the given design.
if (FALSE) { SampleSizePlanner::ssp_power_traditional(tpr = 0.8, delta = 0.5, max_n = 5000, alpha = 0.05) }
