Sorry about that Nick. 

The panel data set that I have, has 467 groups with 27 months as mean length of follow-up. The variable, say 'x', I am referring to is continuous and is dynamic/ autoregressive in nature. So I tried the dynamic panel models.
Xtabond did not seem to work may be because the dataset is unbalanced in nature. Next, I tried xtdpdsys and xtdpd model, but they said 'no observations'. I believe, I am going wrong in specifying the model.

I am interested in running a model that uses at least two lags of the variable. Currently, I have no independent variables. Let me know if more clarification is needed.

Try _not shouting please_ and -summarize- on the same variables.
