What do you say about researchers who think that lag number should be selected to satisfy the assumption of residuals being free of autocorrelation? I ask because, according to the below source, as implied, if the lag number suggested by any known information criteria generate VAR residuals with autocorrelation, the researcher may follow Hendy et. al. to use the lag number which frees the model of autocorrelation. For example, for a time sries instead of 1 or 2 lags, a researcher may use the lowest lag number which frees the model of autocorrelation. Please kindly clarify for me what your position is on that. Hendry, D. F. and Juselius, K. (2001), `Explaining Cointegration Analysis: Part II', Energy Journal 22(1), 75. Ji sie ike.

That's means based on your guide I should use ARDL and NOT the Johansen test since the order is different right? Then I run the ARDL equation and do the bound test. equation A, F-stats higher than Upper bound > means there is cointegration so I need to do ECM. Equation B, also show cointegration and needed to do ECM. Equation C show no cointegration then I just run the ARDL short run model. When I finally do the equation D, the F-stats results between the lower and upper bound. Based on your tutorial that's mean the result is inconclusive. What should I do with the equation D?

So I proceed error correction form. When I check the result, No long run coefficients are significant at all. Then I change the regression method, OLS by means of extracting residual. Under this method most short run coefficients become significant which do not in the former model and also found different result for ect and long run coefficients. Here, my question is (1) what should I do if absolute t stats value against the result of F value. (2) can I use ARDL in both OLS method and ARDL method alternately. (OR) which method is better.
