So in effect, I wish to perform a sample size calculation for aregression coefficient of two variables with unit standard deviation. Inthis case the standard error of the regression coefficient issqrt((1-(b*b))/(n-2)), so standard deviation of the regressioncoefficient is approximately sqrt(...
Elements of sample size calculation Regardless of the nature of outcome (i.e. binary, discrete or continuous), sample size depends on four essential elements: the type I error rate (α), the type II error rate (β), the target effect size, the variability of the outcome measure. These ...
Calculate sample size Technical note Calculation based on the formula: n = f(α/2, β) × [p1× (100 − p1) + p2× (100 − p2)] / (p2 − p1)2 where p1 and p2 are the percent 'success' in the control and experimental group respectively, and f(α, β) = [Φ-1(α...
