Dear scholars, I would like to ask some questions regarding panel data analysis. Currently, I am using panel data of seven cross sections and time series of 33 years. My question is that can I employ xtdcce2? As I read some literature, Dynamic Common Correlate Effect (DCCE) is applicable for large T and N, others suggest that for N25, KAO and Pedroni co-intergartion are applicable. Still, some use it for the same case. Thus, let you suggest me appropriate model that you know from your experience. Thanks in advance.
