The natural filtration
WebFeb 10, 2024 · F t = σ(Xs:s ≤t). ℱ t = σ ( X s: s ≤ t). This defines the smallest filtration to which X X is adapted, known as the natural filtration of X X. Given a filtration, there are various limiting σ σ -algebras which can be defined. The values at plus and minus infinity are F ∞ =σ(⋃ t F t), F −∞ = ⋂ t F t, ℱ ∞ = σ ( ⋃ t ℱ t), ℱ - ∞ = ⋂ t ℱ t, WebApr 5, 2024 · The MarketWatch News Department was not involved in the creation of this content.
