WebTo explain, we recall the basic definitions of the classical hypothesis testing which traditionally involve the so-called parameter space Θ. This set indexes all possible probability distributions of the observed data. A subset Θ0 of Θ corresponding to special parametric values of interest is the null hypothesis H0: θ ∈ Θ0. In many ...
