powerF function

Power Function for the General Linear F-Test

A function to calculate the power of the general linear F-test.

power.F(full, reduced, alpha = 0.05)

Arguments

• full: The full model (specified in the alternative hypothesis) in the general linear F-test. This is an object of class lm.
• reduced: The reduced model (specified in the null hypothesis) in the general linear F-test. This is an object of class lm.
• alpha: Significance level of the test. Default level is 0.05. ## Returns

power.F returns a single value (saved as a matrix) with the power for the corresponding general linear F-test. ## See Also

Examples

## Applied to the toy dataset.

data(toy)

full <- lm(y~x, data = toy)
reduced <- lm(y~1, data = toy)
power.F(full = full, reduced = reduced, alpha = 0.05)
