WebIn the first step I do a GARCH (1,1) fit on Y. In the second step I would like to input X as an exogenous variable into the model. Afterwards it would be useful if I could compare both models (the goodness of the respective fit) by AIC and BIC, and if possible save the residuals for both models. As far as I know rugarch would be the correct ... WebMar 30, 2024 · I am currently writing my dissertation on crypto volatility, and am trying to use RATS for a multivariate GARCH model.

Using RATS to run a multivariate GARCH model with dummy variables
WebOct 24, 2024 · He found the GARCH model with asymmetric influence that was incorporated by using a dummy variable model to be the most successful in forecasting the volatility of the Bucharest Exchange Trading Index (BET). The results provide strong evidence indicating that daily returns can be measured by GARCH-type models, … Webthis difficulty, we estimate the GARCH(1, 1) model for daily stock returns over a relatively large range of data (4,228 observations), including dummy variables for arbitrarily chosen subsamples. We choose to allow for structural shifts every 302 observations; that is, k = 13 mutually independent dummy variables are in-cluded in (6). magnesium cyanide chemical formula
