WebWhen modeling multivariate garch (where there was a lot of choice in parameterization), it seemed to be that BIC was defnitely better than AIC. BIC has a larger penalty and so suggests smaller models. It looked like the penalty should be even bigger than in BIC -- that the BIC models were still too big. Share Cite Improve this answer Follow WebNov 29, 2024 · Akaike information criterion ( AIC) is a single number score that can be used to determine which of multiple models is most likely to be the best model for a given data set. It estimates models relatively, meaning that AIC scores are only useful in comparison with other AIC scores for the same data set. A lower AIC score is better.

WebThe specific details of the MS-GARCH model are given in Section 3.2. The main work of this study is to construct a multi-regime switching model considering structural breaks (ARIMA-MS-GARCH) to predict the daily streamflow time series. Specifically, the Bai and Perron (2003) test was used to identify structural breaks in the daily streamflow ...
