Help with ARDL model

[sir_alex92]

Hello!
I'm a student in VietNam and i'm studying about the ARDL model for my research papers. The problem is i cant find any textbook or document about this model. Can you guy please help me out by share with some training documents, practice book...anything you think is helpful. I'll be very appreciate.
One more thing, i'm reading a papers which using the ARDL model and it has these information about the estimated ARLD model:
ARDL(2,1,1,1,1,0)
ARDL(9,10,8,9,9,8)
Since i'm new to ARDL and eviews, i actually dont understand these numbers. Can you guys explain it's for me. Thank you all!
