Abstract:
Abstract The σ $$\sigma $$ -algebra generated by a random variable X, denoted σ ( X ) $$\sigma (X)$$ , is the σ $$\sigma $$ -algebra by the collection of { X ∈ B } $$\{X \in B\}$$ (i.e., { ω : X ( ω ) ∈ B } $$\{\omega : X(\omega ) \in B\}$$ ), where B is any interval in ℝ $${\mathbb {R}}$$ . Let G $$\mathscr {G}$$ be a σ $$\sigma $$ -algebra on Ω $$\varOmega $$ . Then X is said to be G $$\mathscr {G}$$ -measurableMeasurable if σ ( X ) ⊆ G $$\sigma (X) \subseteq \mathscr {G}$$ .
