power.onesampt {FDRsampsize}

Compute power of the one-sample t-test

Description

Estimate power of the one-sample t-test;Uses classical power formula for one-sample t-test

Usage

power.onesampt (n, alpha, delta, sigma = 1) 

Arguments

n

number of events (scalar)

alpha

p-value threshold (scalar)

delta

difference of actual mean from null mean (vector)

sigma

standard deviation (vector or scalar, default=1)

Value

vector of power estimates for two-sided test

Examples

 power.onesampt        # show the power function
 res=fdr.sampsize(fdr=0.1,
                  ave.pow=0.8,
                  pow.func=power.onesampt,
                  eff.size=rep(c(2,0),c(100,900)),
                  null.effect=0,
                  sigma=1)
