WebBollerslev (1986) extended the model by including lagged conditional volatility terms, creating GARCH models. Below is the formulation of a GARCH model: y t ∼ N ( μ, σ t 2) σ t 2 = ω + α ϵ t 2 + β σ t − 1 2. We need to impose constraints on this model to ensure the volatility is over 1, in particular ω, α, β > 0. WebProject’s Overview.
