power.signtest | R Documentation |
Use the Noether (1987) formula to compute the power of the sign test, which is based on asymptotic normal approximation.
power.signtest(n, alpha, p)
n |
sample size (scalar) |
alpha |
p-value threshold (scalar) |
p |
Pr(X>0), as in Noether (JASA 1987) |
In most applications, the null effect size will be designated by p = 0.5

p = rep(c(0.8,0.5),c(100,900));
res = power.signtest(n = 50, alpha = 0.05, p = p)
