WebJul 8, 2024 · $\begingroup$ ARMA is a mean model, whereas GARCH is a variance model. If the underlying time series is known to be 0 mean, then we can apply GARCH directly. Otherwise the mean needs to be estimated. If not, the dynamics of mean will leak into variance estimation and we will not be able to distinguish them. WebGARCH(1,1) models are favored over other stochastic volatility models by many economists due 2. to their relatively simple implementation: since they are given by stochastic di erence equations in discrete time, the likelihood function is easier to handle than continuous-time models, and since nancial data is generally gathered at discrete ...
