Hi Arshed, Many thanks for your video. I would like to ask you one question: how can the stability test of an ARDL model be performed with R? I would like to check whether the inverse roots of the characteristic equation are lower than 1 but I don't know how to perform it with R (with EViews, this test is easy to perform). Thank you so much for your reply and your commitment. Kind regards :)
Hi Sab, I have the exact same question. If you manage to find an answer please let me know! The ardlBound function tests stability using cumulative sums and cumulative sums of squares, which is also done in some papers, but other papers do it differently...
@@gabrieldunin-borkowski201 Hi Gabriel, Sure I will let you know if I find the answer! I follow the following procedure: davegiles.blogspot.com/2013/06/ardl-models-part-ii-bounds-tests.html This is why I think that it is important to test whether the model is dynamic stable. Kind regards
Thankyou Sir. I want to ask you some question. While I run bound f test there is cointegration and I run UECM the long run variable which is statically significance, but when I run multiple(ardl) the variable is insignificant . Is there any problem with this? Please help me !
Dear Arshed, May I ask you a question. I would like to test cointegration by f test (bound test) in panel data. Is there any command in stata ? thank you very much.
Hello sir, i am not able to install many of the packages in R to enable me do the estimation. Example, i tried to install ARDL package and this is the feedback i got; "Error in install.packages : cannot open file 'C:/Users/User/Documents/R/win-library/4.0/file71f840e55f61/expm/doc/expm.pdf': Permission denied". In cases like this, what should i do?
Thank you Sir to clear the concept why some time command is not working. I admire you.
You migh have to install them or share the error i will see
This video is really knowledgeable and helpful , thank you
Welcome

They may not have long run effect. Or try changing lag order to see if you can get better results otherwise you might have to change variables
Do you mind sharing the data you used in this exercise.
sir there is NA NA in most of the value residuals are nas why?
Estimation cannot be done in a row of data in which any one variable is NA so residuals are also NA
packages (AIC and BIC) please
These packages are already built in ARDL library
Please a video about midas-ardl: midasml package, thank you sir
Soon
sir, kindly help me to overcome the issue of the serial correlation in the ardl model.
For that change the lag order
Hi Noman. Thank you very much for this video. Is it ok for you to share the data? I would like to follow your R codes. Thank you so much.
You can follow codes using ruclips.net/video/7tCTaO2hGgY/видео.html
Dear Arshed, May I ask you a question. I would like to test cointegration by f test (bound test) in panel data. Is there any command in stata ? thank you very much.
There is no f bound test in panel data. You may apply bound test to individual panels by making then time series data.
sir, what package ardlbound is? cus i can't found it
The library is dLagM

Your computer is not allowing new files to be installed by R. Kindly allow R to install in your antivirus or security software
thank you mr arshed
i have some question, i was wondering if you could send me your email.
all the best
