Sayed Irshad Hussain

Dear Javed First, thanks a lot

Please guide me how can i run the bond test equation in stata for cointegrtion. i write the possible step please correct me if i am not doing in right way

First i run the the standard ardl model at best lags order

then i apply this ardl, noctable btest option

and if there is co integration relation

then i calculate the long run model that is ardl, and short run that is ecm

please correct me if i am not doing in right way

Please mention the bond testing command or procedure

Please also mention how to check the stability of coefficients in stata,

thanks and best regards

Irshad

I am analyzing a panel data set containing 17 years data for 107 countries and export value is my dependent variable while having 8 independent variables. I want to asses the long run short run relationship of my dependent and independent variables. I found that my dependent variable and six independent variables are stationary at level where as other 2 inependent variables are stationary at I(1). My first question is can I apply ARDL model for my data? My data in natural log form because of my model is in natural log form. My another problem is I have many negative log values in my data set and many missing values as well. I want to know whether this type of daat will support to perform ARDL test in STATA? Is there any limitation of number of independent variables can be accomodated in ARDL model? I have stucked with my master thesis at this point.

@ Ume Salma Akbar

If I have the optimal lag to use in ARDL, how can I specify the lag in the equation you mentioned?

@Suleman Abas

ardl lnX1 lnX2 , lag(...)

...= What ever optimal lag number is

I hope it is clear to you.
