Hi, My name is Luke and I come from Poland. I have one question, maybe very simple, but I can not resolve it. In dynamic panel data (GMM estimator) after running the model, I recieve a AR test and Sargan test, but the "number of instruments" are not displayed. In Stata and Gretl this informatios is given, in R no. My question is, how to obtain the number of instruments?. Thank you for helping. Luke
