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).
I am interested in knowing how can I apply the Windmeijer's correction on xtiverg2 gmm2s cluster(id).
The Windmeijer correction is for Arellano-Bond and Blundell-Bond "DPD" models. xtivreg2 by Mark Schaffer does not estimate those DPD models. 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.
When you say you have only 156 obs. in the subsample, what is N and what is the average T?
