Hi,
Myself Subhash, an Economics graduate from IIT Kanpur. I have done many projects that required the use of econometric analysis techniques like Stationarity test, Cointegration, VECM/VAR, ARDL, ARIMA models. I can send you the sample reports. I assure you that i will provide best quality work.
Use of Cointegration and VECM depends on results of Unit root test. If some variables are I(1) and some variables are I(2), then we should use ARDL method.
Thanks & Regards,
Subhash
