Increasing the lag or differentiating the variable up to 3 three times does not resolve the issue! Interesting enough the unit root test says there is no unit root in level (daily frequency).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6883247404678549489.post-58848739813935594842022-10-17T12:32:26.566-07:002022-10-17T12:32:26.566-07:00What you're asking cannot be done automaticall...What you're asking cannot be done automatically. Nevertheless, since (N)ARDL estimation is estimated using least squares (LS), what you want can be done manually. <br /><br />After estimating a NARDL equation, proceed to View/Representations. From here, copy the string after "Estimation Equation:". Use this string to remove the variables you don't want and use the remaining string to estimate a basic least squares regression.IHSEViewshttps://www.blogger.com/profile/04703437003033046408noreply@blogger.comtag:blogger.com,1999:blog-6883247404678549489.post-65034402073608851332022-10-17T10:26:22.464-07:002022-10-17T10:26:22.464-07:00Thanks again.

Journal of Economic Dynamics and Control", is there any way to separate the positive in EViews?<br /><br />I know it is possible to choose lags in EViews, but do not know how to single out + vs - ones, since even I cannot save those lags or differenced variables to use them in the equation.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6883247404678549489.post-87309213013325595822022-10-17T10:20:11.753-07:002022-10-17T10:20:11.753-07:00Hello there!

These Wald tests are based on the coefficients of the CEC (default) regression output. In other words, there can only ever be a single situation in which you have the scenario you're talking about and that is that the individual coefficients are insignificant (probably very slightly only), but jointly, they are significant. In this case, you will take the results of the joint test to conclude that asymmetry is indeed valid.IHSEViewshttps://www.blogger.com/profile/04703437003033046408noreply@blogger.comtag:blogger.com,1999:blog-6883247404678549489.post-67702910274409602662022-10-16T14:54:07.636-07:002022-10-16T14:54:07.636-07:00hi-- If the coefficients for partial sum of positi...hi-- If the coefficients for partial sum of positive and negative effects are NOT significant, but the asymmetry test shows that there is an asymmetric effect exists for that variable, what is the inference in this case?<br />tnxAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6883247404678549489.post-77669149791858264892022-10-16T09:27:20.395-07:002022-10-16T09:27:20.395-07:00Thanks for your guidance.

I realized that whenever I want to perform a NARDL analysis, I get the response "invalid or duplicate specficiation". I use daily log returns of S&P 500, Apple, and VIX. I also tried to use the dataset here (Toursim in Bosnia) I get the same error. I exactly do the same thing that you do here. What should I do? <br />ARDL works but NARDL I get this error.
