I am currently having a dataset of T=10+ and N=26, and will most likely use the LSDVC estimate by Kievit and GMM, according to the paper by Judson, Owen (1999),Roodman(2009). Unfortunately, I am now questioning whether GMM or panel ARDL to apply?
Enlarging to T=10+ would be possible to change according to model requirements but N is fixed .
Thanks already and best regards
