The output of the fitted model (use the command intc_garch11_fit) reveals useful information, such as the values of the optimal parameters, the value of the log-likelihood function, and the information criteria. Backtesting the risk model A useful test for checking the model performance is to do a historical backtest. In a risk model backtest, we compare the estimated VaR with the actual return over the period.

The no-arbitrage argument will force consistency in the prices of the derivative and underlying assets there. The objective of this chapter is to present the relationship between the asset return and the risk factor. We will explain how to download and clean data from multiple sources. Linear regression is used to measure the dependence and the connected hypothesis test shows the significance of the results. The one-factor index model is tested through a two-step regression process and the financial interpretation of the results is shown.

We have thus discovered two cointegrated variables and can proceed with the second step; that is, the specification of an Error-Correction Model (ECM). The ECM represents a dynamic model of how (and how fast) the system moves back to the static equilibrium estimated earlier and is stored in the mod_static variable. 45117 Coefficients: Estimate Std. 909 <2e-16 *** --Signif. 06875). 65540): large deviations between the two prices are going to be corrected and prices move closer to their long-run stable relationship.
