The Problem
ASSERTION: Such emphasis is not typically in keeping with the state of knowledge as an experiment is being conducted
The parametric assumptions are more detailed than the hypothesis being tested, e.g.,:
·Question: How does the intervention affect the first moment of the probability distribution?
·Assumption: We know how the intervention affects the 2nd, 3rd, …, ∞ central moments of the probability distribution.
