Garch methodology
WebThis paper presents a new method for identifying triangular systems of time‐series data. Identification is the product of a bivariate GARCH process.

The lines below use the function ugarchfit to fit each GARCH model for each ticker and extract \(\hat\sigma_t^2\). Note that these are in-sample volatilities because the entire time series is used to fit the GARCH model. In most applications, however, this is sufficient.
