3. Parametric tests

Consider the statistical model (Ω, $\mathcal{A}$ , (P _θ ) _{θ ∊Θ} ). The distribution P _θ of X is assumed to be known, with parameter θ ∊ Θ ∊ $ℝ$ unknown.

We assume that Θ is divided into a part Θ ₀ and its complement Θ ₁ . Parametric tests are used to test the hypothesis H ₀ : θ ∊ Θ ₀ ...
