Dear all,
I am using the Phillips and Sul (2007) technique for convergence test and club identification for my PhD research. My problem is that sometimes, for one of the clubs identified (with the psecta and default options), the TStat in the output table is below the threshold value of -1.65, whereas if I use the adjusted method (Schnurbus, 2017) with the same dataset, therefore including the 'adjust' command specification, the results are ok. On the contrary, when using a different dataset, the same problem (with the TStat value below -1.65 for one of the clubs) happens when using the adjusted method, while the other method is ok.
How can I handle the issue? Why does it happen? Should I use some specific options or just discard the anomalous clustering obtained and choose the alternative method? How can I motivate this in my PhD research?
Thank you very much in advance for your reply, I really hope you can help me!
