st: shord dynamic panel: xtlsdvc or ivreg2?

["sistoand80" <sistoand80@libero.it>]

Dear Statalisters,
I need to estimate a short dynamic panel (T=6 and N=20). Two possibilities:
(1) lsdvc
(2) ivreg2 with dummies (model in level and lagged dependnet variable instrumented in level with l2.y and l2.X)
What do you suggest?
