I am using the function wp.regression() and setting the alpha parameter to 0.05. However it's not clear whether it is computing a one-tailed or two-tailed test. Which test is default, and can I specify that one-tailed is required?
power
alpha
two-tailed
one-tailed

It only used two-sided test ~ An F-test is used.

Thanks for your answer - do you know of any way I could conduct a one-tailed test instead with wp.regression()?
