Creates a link object based on the link function \(\eta = \mu ^ \lambda\).

power(lambda = 1)

a real number.

A list with components linkfun, linkinv, mu.eta, and valideta. See make.link for information on their meaning.

If lambda is non-positive, it is taken as zero, and the log link is obtained. The default lambda = 1 gives the identity link.

To calculate the power of a test, see various functions in the stats package, e.g., power.t.test.
