Statistical Hypothesis Testing

Care must be taken in setting up the hypothesis test to ensure that the analysis performed addresses the test objective. Too often DoD testing includes “implied” hypothesis tests in which the actual hypotheses are never explicitly stated!

Chapter 3 Total variation distance between measures
www.stat.yale.edu4 Chapter 3: Total variation distance between measures If λ is a dominating (nonnegative measure) for which dµ/dλ = m and dν/dλ = n then d(µ∨ν) dλ = max(m,n) and d(µ∧ν) dλ = min(m,n) a.e. [λ]. In particular, the nonnegative measures defined by dµ +/dλ:= m and dµ−/dλ:= m− are the smallest measures for whichµ+A ≥ µA ≥−µ−A for all A ∈ A. Remark. Note that the ...
