power.exp {dae} | R Documentation |
Computes the power for an experiment.
power.exp(rm=5., df.num=1., df.denom=10., delta=1., sigma=1., alpha=0.05, print=FALSE)
rm |
The number of observations used in computing a mean. |
df.num |
The degrees of freedom of the numerator of the F for testing the term involving the means. |
df.denom |
The degrees of freedom of the denominator of the F for testing the term involving the means. |
delta |
The true difference between a pair of means. |
sigma |
The population standard deviation. |
alpha |
The significance level to be used. |
print |
TRUE or FALSE to have or not have a table of power calculation details printed out. |
A scalar containing the computed power.
rm <- 5 power.exp(rm = rm, df.num = 3, df.denom = 3 * (rm - 1), delta = 5, sigma = sqrt(20),power = 0.8, print = TRUE)
