Thank you Kit for your useful input. The model I am estimating using xtivreg2 gmm2s cluster(id) is a static model and not dynamic. In the subsample N is 45, average T is 4.1 and the total number of observations are 185.

> Thank you Anees for your help. I have read all the relevant literature in detail. I have used xtabond2 for my dataset, now I want to analyse the subsample for something. The problem is the number of observations is 156 in the sub sample and I cant apply xtabond2 because of small sample size. I have applied xtivreg2 and now I want to correct the estimates for small sample size bias (Windmiejer's correction).

It would not be appropriate to apply xtivreg2 with fixed effects to a dynamic panel model. The fact that xtivreg2 (and the underlying ivreg2 of Baum-Schaffer-Stillman) has a GMM option does not mean that it can consistently estimate dynamic panel models.
