![]() i did a pre-test, and i got a really high r-squared(91%) which is absolutely scary.does the r-squared matter in the ARDL model just like how the durbin watson is inappropriate in the ARDL model. ![]() secondly, when constructing the ECM from the usual OLS regression do i still need to include break and in the model specification as i have included in the ardl model? thirdly, if i supposedly find co integration, do i need to explain the break coefficient included which is a mixture 2 independent variables? or do i need to construct individual break for each independent variable?(i used the chow breakpoint test initially, to determine both simultaneously). I have a sample range from-2014 quarterly data(64 observations).i used the NG-perron unit root test which is relatively more accurate for sample samples as against the other traditional tests.i have 3 variables in total, mixture of I(1) and I(0).is it worth trying the ARDL bound test.
