Initially, the series is observed to be a stationary one, and optimal autoregressive moving average model is estimated. Later, it has been revealed that the residuals of the mean equation implicate ARCH effect. In addition, heteroscedastic variance model with four different conditions / assumptions has been estimated. It has been proven that ARCH effect is eliminated in these models estimated and no autocorrelation exists in error terms, either. As a result, it has been revealed that among these models the optimal conditional heteroskedasticity model is the TGARCHeninfo:eu-repo/semantics/openAccessEuroVolatilityHeteroskedasticityArticle3103441
