Hello,
I estimates FIGARCH model using rugarch package. While model specification by the function ugarchspec(...), one of its argument is distribution.model that specifies the conditional density to use for the innovations. By the theory, the innovations needs to have zero mean and unit variance, so need to be standardized.
So my question is, whether setting the argument to the values "norm" or "std" corresponds to the standardized normal and standardized student t-distribution???
Thank you very much!
