If you are interested in finding out non correlated sequence/items in your time series , why don't u just apply ACF/PACT to find out lagged number (p). And then, I reckon, this p +1 would be your n, as there won't be much autocorrelation between these items.

My answer is based on the fact that the above equations corresponds to the provided STATA code and output. Thus, I disregard my own questions in the comments below the post.
Consider bounding your GJR-GARCH parameters:
You need to bound your parameters in order to ensure positivity (positive estimates) and covariance stationarity. I will disregard the mean-...

If the company is seeking external funding, normalized financial statements provide the investor or lender with a clear picture of the actual expenses, revenues, earnings and cash flow of the company during a ...

ADF tests for a unit root. Autocorrelation function of a unit root process does not make sense. For example let
$$y_{t+1}=y_t+\epsilon_{t+1}$$
Here $\epsilon_t$ is i.i.d white noise. Then the one period autocovariance is
$$Cov(y_{t+1},y_{t})=Cov(y_t+\epsilon_{t+1},y_{t})=Var(y_t)$$
For a unit root process $Var(y_t) \rightarrow \infty$ as $t\rightarrow \infty$...

You will not be able to replicate positive decaying autocorrelations in current markets:
Due to the increased popularity in high-frequency trading, there's been a likewise increased focus on studying the underlying empirical properties of high-frequency data. One of the stylized facts in high-frequency data is the significant first-order negative ...
