I want to know, How to interpret this correlogram? How many ARIMA model and what is the number of p and q for ARIMA? Thanks

I would like to know, how can i type an equation of ARIMA(2,1,1)-GARCH(1,0) and what method for this equation? Can i use ls method? How about an equation for ARIMA(2,1,1)-GARCH(1,1) and ARIMA(2,1,1)-GARCH(2,1) Thank you.

Can i put the independent variables after ma(1)? For example d(y) c x ar(1) ar(2) ma(1) df dg dh.

i got it. Thanks

thank you, but i want to know, why i have to type ar 2 times. I'm so confused.

If my arima model is 2,1,1, What i should type in my estimate equation for run this model or equation
