GARCH output basic question

#1
This is likely an absurdly basic question, but how are the parameter estimates in a GARCH(1,1) model interpreted...specifically the AR1, AR2, ARCH0, ARCH1, and GARCH1?

Here's a copy of my output:


Algorithm converged.

Thanks for any help. I know the sample size is way too small for a GARCH model, but this is a preliminary run of data...there'll be a few thousand observations once the collection is done at the end of the year.

I found an HC3 macro to use on the small sample to deal with the heteroskedasticity, but a) I can't figure out how to also deal with autocorrelation when using the macro; and b) I want to account for volatility, not necessarily have homoskedastic errors. If anyone thinks there is a better way to do this (dealing with the heterosk., feel free to let me know.

As it stands, I can't find any reliable, not absurdly technical explanation of dealing with the coefficients that the GARCH process adds to the output.

Thanks for the help

Also, if none of my above thinking makes sense, I'd be happy to know that, as well. New to this whole thing, and may be completely off in my thinking/model understanding...
