Equivalence Tests Can Enhance Environmental Science and Management

摘要: Tests of point hypotheses are common in observational environmental studies, but there is concern about their appropriateness. Exhortations to restrict sample sizes on the basis a power analysis for such tests may fail satisfy professional, because not always easily controlled. Testing interval via equiva-lence test procedures offers way testing meaningful and giving effect precautionary principle. An example given which concerns mining impacts stream benthic invertebrate communities, includes calculation Bayesian posterior probabilities.
