Very well explained, Prof. A question though out of curiosity. What is the theoretical justification for including the difference operator in the short run specification?

Dear prof, your video is valuable. at 8:06 when you test for short-run model of no-cointegration equation and using lag 1. Is it because of in the lag length test shows the optimal lag is in lag 1 ?

Yes

How if the result shows p-value above 5% whichs means no short run relation ? Can I solve this problem and make it shows significant relation ?

Hi thank you sir for this really clear video. I want to ask, whether or not you have to include the current year as you did. Because you found optimal lag 1 for LARR. but in another video (maybe from a competitor: crunchmetrix) only the lagged differenced variables are used.

Hi, just a question. Let say we are looking at GDP, Tourism arrival and crime. Were the idea is to get a picture on crime. If for example your ect is -0.85 and we know that there are causality running from long-run values of GDP,Tourism arrival towards crime, can we use the ect equation to see if either GDP or Tourism has a positive or negative relationship with crime? In the short-run dynamics its easy to see from the ARDL model, but the long run dynamics I am not sure. thanks marc

Dear sir, Thank you for your videos on ARDL, they were very helpful. I have a question regarding the short run coefficient interpretation. EViews selected the model ARDL(1,1,0,3,0). Does this mean that in the short sun there is relation between the dependent variable and the one with 0 lags)? This would help a lot. Thank you in advance.
@PatObi4 жыл бұрын
It means that only the contemporaneous term of that regressor affects the dependent variable, if t is significant.

@@PatObi so, when I do the error correction form of the model those that have (0) are not included therefore, I have to look at the initial estimation of the equation and see if they are significant and then interpret the coefficient? Thank you so much!
@Azam_Pakistan5 жыл бұрын
Great reised version. A few queries Sir, do you mean it is sufficient to explain only the contemporaneous term to report short-run causality and not its lags? Secondly if in a joint test these jointly don't turn out to be non-significant but the contemporaneous term is significant, can we interpret the contemporaneous. Grateful.
@PatObi5 жыл бұрын
Thanks for your Q. In my view, all lags should be interpreted, including the current term if significant. Lags convey different meanings in terms of how long the effect of X on Y lasts. Keep in mind the current term (Xt) is part of the lag structure...it has a lag of 0. So yes, it should be interpreted, in my opinion.

Hi Sir, Thank you very much for your informative videos. They have been of great help. However, I am currently still left with two questions. Namely, I have included an exogenous dummy variable in my ARDL model to account for a structural break which previously interfered with the stability of my model. However, when I try to conduct a new Cusum test, it only shows me the time period after the structural break. How can I resolve this? Additionally, what is the added value of assessing the optimal lag length of the ARDL model beforehand? Would it not be possible to select automatic selection, opt for max lag length (12) and let Eviews do the work? Curious to hear your thoughts. Many thanks.

Hi, Thank you very much, that was a quick response from you. I really appreciate. However, from the video link you posted, it was on time series estimation, but my question is on estimating panel ARDL long run/bound test . I am using standalone Eviews 11 academic version and I could not get the long run/bound test from the dialogue box after clicking on the coefficient diagnostics from views to determine the F-stat. If the problem is from the type Eviews Ii am using, which model of Eviews do you recommend I should purchase. Thank you.

If that's the case, then consider getting the full version. Much easier. In the mean time, you can estimate the equation directly as I show in this older ARDL video: kzbin.info/www/bejne/aKWWmmyLe9-KodU

In my bound test i find the data is cointegrated, however i didnt have negative and significant ect in ecm analysis, is that mean cointegrated result in bound test didnt always mean we have cointegration in the long run sir?, Is cointegrated result in bound test only mean we possibly have long relationship and ect result determine whether we have long run relationship or not?, If that so why some people always told the variable is cointegrated in the long run when the they find result in bound test or johansen test is good?

If there are no issues with your data and model, your results may be indicating only a l.r. relationship. May be the variables have no s.r. dynamics.

Good morning Professor, Please Sir, why EViews 10, estimates the short-term equation without the variables having a zero lag? For example; ARDL(2,2,0) Eviews estimates the short-term equation without the third explanatory variable! I.e. we can not calculate the short-term coefficient for these variable? B.w.

The algorithm in EViews considers that to be the parsimonious model.

@@PatObi A related question: is it correct to say that the variable with a 0 lag has no short run impact in the underlying ARDL model (due to the fact that it isn't included in the ECM regression, which is defined in the literature as the short run adjustment)?
