WebbConsequently, we can calculate the p -value of the test ( 1) as p = P H 0 { T n, NEW ≥ t }. Hence, the power function of the test could be given by p ( t) = P { T n, NEW ≥ t }. It may not be easy to derive the distribution of T n, NEW in practice, we therefore alternatively calculate the p -value by Monte Carlo simulation.
