Abstract

The importance of using self-regression models is conditional after smoothing the variance with the fluctuations of the daily closing price of gold globally for the period 1/1/2023 until 26/12/2024, including the GARCH-M(p,q) and TEGARCH(p, q)models, and diagnosing the models with the problem of heterogeneity of variation, estimating the parameters of the models used in the greatest possible way, examining the models using tests and statistical criteria to obtain the best models that represent real data, and then processing them using the Daubechies Wavelet and the Symlets  Wavelet, and examining the suitability of forecasting models, it turned out that processing data with a wave gives better results than in real data, since a model with fewer parameters was obtained, which is the TGARCH model(1,1).
