Abstract:
|
P-values can be useful measures of evidence against a null hypothesis. In contrast to parameter estimates, however, their sample-to-sample variability is usually not considered or estimated. Standard errors on the log scale and bootstrap prediction intervals for p-values are presented that reveal a surprisingly large variability in typical data situations. One conclusion might be to question the importance of exact p-values relative to asymptotic or Monte Carlo approximations. Another conclusion might be that the use of *, **, and *** to denote levels of statistical significance in subject matter journals is about the right level of detail rather than reporting actual p-values.
