WebThe conditional mean, µt, is typically of secondary importance for GARCH-type models. The primary objective is the conditional variance, σ2 t, which is modelled by h2 t = σ 2(F t−1; θ). (2) In financial time-series, it is often important to model the distribution with a … WebOct 20, 2024 · In this paper, we incorporate a GARCH model into an artificial neural network (ANN) for financial volatility modeling and estimate the parameters in Tensorflow. Our goal was to better predict stock volatility. We evaluate the performance of the models using the mean absolute errors of powers of the out-of-sample returns between 2 March …
