The link between alpha-level tests and p-values is stated in terms of a power
surface and is demonstrated visually using tests based on continuous and
discrete test statistics. Cross-sections of the power surface in one plane
result in the usual power curves, while cross-sections in another plane
provide a useful empirical tool for evaluating tests. Examples are given
using Monte-Carlo simulation and bootstrap techniques.
