how about checking the long-run causality test in ARDL?....or just checking short-run causality is good enough to infer the direction of the causality? Thanks
Thanks for the quality of sessions you upload. Can i used this method on panel data? Kindly help in identifying methods that do apply to panel data and for time series data
Thanks for the informative sessions. I have been watching them over and over again. I noted that on this video you didn't un-check the automatic lag selection box to allow for the fixed lag selection. How does this affect your results?
Hi Menzi, thanks for the positive feedback. Deeply appreciated! My suggestion will be that you estimate both variants and observe your findings. It is the best way to learn. Please may I know from where (location) you are reaching me?
@@CrunchEconometrix Reaching out from the Kingdom of Eswatini. My inferences from the results are not the same when I fix the laggs based on the lags prescribed from conducting the lag length criteria. Thanks I will try to find a way out.
Thank you this nice tutorial dear professor, when trying to estimate a model using the ARDL it gives me an error message that there is a singular matrix, what is the source of this problem? and what are the possible solution?
I am sorry I am not quite there on the same line as you are. In previous video's I had 3 variables with the dependent variable: an I(1) integrated variable & independent variables I(0). So I estimated ARDL, took lag length 1 for these models while I have 41 years of data and constant (model 3). Then I checked for cointegration for the 3 ARDL models and concluded 2 cointegration and 1 no cointegration. So I specified 2 long run models and used the residuals for the ECM model to be estimated with OLS. Same for the variable with no cointegration I conducted ARDL analysis with the optimal lag length specified in the VAR model in Eviews like you have done.. So no causality should be checked for this last one. There are no significant coefficients for this ARDL model, short run model. Is my procedure correct?
Good day Dr. Sorry for disturbing again. I tried to watch your videos for the ARDL model but is still have a question. my question is my dependent variable the optimal lag is 1, one of the independent variables has 1 optimal lag and another one has 2 optimal lags. What should I choose for max lags?
hello, please i need to konw how to perform conditional granger causality test in eviews ? i know that there is an add-ins called "spectal causality" in eviews but i don't know how to use it. Any help would he greatly appreciated
hi i want to ask how an ARDL model can be run if structural breaks are found? your video on structural break is not telling after the CUSUMSQ is done with breaks
Hello Ma'am...plz clear doubts regarding ARDL... 1. If all variables are stationary at first difference... should i use level data or first diff data for ARDL. 2. Why option 3(contant) is selected as i noticed in videos. Should i check graph before selection of constant or constant and trend?? Thanx
Hi Ajay, use level data if estimating with ARDL algorithm. Use 1st diff series if estimating with OLS. I have explained this in my videos. The assumption for case 3 is that the constant of the model is unrestricted. You can observe the trend of any series by plotting the graph. Thanks.
Hlo Ma'am.. I m asking question again...i converted all variables into natural logrithm then all variables r stationary at first diff. Should i use first diff data or level data for ARDL?? Not clear about ARDL alogrithm and ARDL ols as u replied Ma'am. Thanx
Ma'am ... yesterday, you replied my doubts relating to ARDL ... use level data for ARDL alogrithm and first diff data for ols. I m not clear about... whats diff b/w ARDL alogrithm and ARDL ols so i asked...

Hi Mohamad, I explained LR causality using the ECT of the models.
Thank you so much@@CrunchEconometrix
Thank you.Would you tell me What is the stata command for ardl granger causality tests?
Mahinur, kindly watch my ARDL Causality videos.
This is really helpful. But what I wanted to know is that the max lag test is the same thing that you did for a VAR system?
Thanks for the positive feedback. You can either use that approach OR let EViews choose the optimum lags. I showed this in several EViews ARDL videos.
@@CrunchEconometrix Cool. I think I came across it but I will check it over to refresh my memory. Thanks once again.

Time series and panel data analytics differ. I have videos on both. Kindly watch to know what suits your study. Thanks.
I practice the ARDL model on eview with 6 variables (they are stationary) but the result is singular matrix. I have to practice how to fix this
Multicollinearity problem. I have a video on it. Watch it to know how to fix the problem.

I have a question why do interpret the coefficients of the ARDL model as "short" run causality? do you have any reference for that?
Hi Muhammad, this video is well explained with references provided in my ARDL videos. Thanks
@@CrunchEconometrix thanks alot 🙏🙏🙏
Thank you very much for the tutorial.. but I have a question in minute 04:37..how do we determine this max lags for each variable? thanks

Thank you this nice tutorial dear professor, when trying to estimate a model using the ARDL it gives me an error message that there is a singular matrix, what is the source of this problem? and what are the possible solution?
Hi Mohammed, it means there is multicollinearity. Please watch my video on MULTICOLLINEARITY on how to resolve this, thanks.

plus causality tests should be performed on the OLS regressions of the 2 EC models that I found like you did here (same steps)?
Once you have clearly followed the steps, you will know if you are on track or not.
My Causality videos are well-explained with guides on what to do. Kindly watch them again and jot some notes while at it.
